    descriptionThe SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575] CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker

"The SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to
receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: Attackers used to be able to track the Linux kernel by
the IP ID values the kernel produces for connection-less protocols.
When such traffic was sent to multiple destination IP addresses, it
was possible to obtain hash collisions (of indices to the counter
array) and thereby obtain the hashing key (via enumeration). An attack
could have been conducted by hosting a crafted web page that uses
WebRTC or gQUIC to force UDP traffic to attacker-controlled IP
addresses. [bnc#1140575]

CVE-2019-10639: The Linux kernel used to allow Information Exposure
(partial kernel address disclosure), leading to a KASLR bypass.
Specifically, it was possible to extract the KASLR kernel image offset
using the IP ID values the kernel produces for connection-less
protocols. When such traffic was sent to multiple destination IP
addresses, it was possible to obtain hash collisions (of indices to
the counter array) and thereby obtain the hashing key (via
enumeration). This key contains enough bits from a kernel address (of
a static variable) so when the key was extracted (via enumeration),
the offset of the kernel image was exposed. This attack could be
carried out remotely by the attacker forcing the target device to send
UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a
server to send UDP traffic is trivial if the server is a DNS server.
ICMP traffic is trivial if the server answers ICMP Echo requests
(ping). For client targets, if the target visits the attacker's web
page, then WebRTC or gQUIC can be used to force UDP traffic to
attacker-controlled IP addresses. [bnc#1140577]

CVE-2018-20836: A race condition used to exist in smp_task_timedout()
and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to
a use-after-free. [bnc#1134395]

CVE-2019-10126: A heap-based buffer overflow in the wireless driver
code was fixed. This issue might have lead to memory corruption and
possibly other consequences. [bnc#1136935]

CVE-2019-11599: The coredump implementation did not use locking or
other mechanisms to prevent vma layout or vma flags changes while it
ran, which allowed local users to obtain sensitive information, cause
a denial of service, or possibly have unspecified other impact by
triggering a race condition with mmget_not_zero or get_task_mm calls.
[bnc#1131645].

CVE-2019-12614: There was an unchecked kstrdup of prop->name on
PowerPC platforms, which allowed an attacker to cause a denial of
service (NULL pointer dereference and system crash). [bnc#1137194]

CVE-2018-16871: A flaw was found in the NFS implementation. An
attacker who was able to mount an exported NFS filesystem was able to
trigger a NULL pointer dereference by an invalid NFS sequence. This
could panic the machine and deny access to the NFS server. Any
outstanding disk writes to the NFS server will were lost.
[bnc#1137103]

CVE-2019-12819: The function __mdiobus_register() used to call
put_device(), which would trigger a fixed_mdio_bus_init use-after-free
error. This would cause a denial of service. [bnc#1138291]

CVE-2019-12818: The nfc_llcp_build_tlv function in
net/nfc/llcp_commands.c may return NULL. If the caller did not check
for this, it could trigger a NULL pointer dereference. This would
cause denial of service. [bnc#1138293]

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
allowed local users to cause a denial of service or possibly have
unspecified other impact by changing the value of ioc_number between
two kernel reads of that value, aka a 'double fetch' vulnerability.
[bsc#1136922]

CVE-2019-12380: An issue was in the EFI subsystem existed that
mishandled memory allocation failures. Note, however, that all
relevant code runs only at boot-time, before any user processes are
started. Therefore, there was no possibility for an unprivileged user
to exploit this issue. [bnc#1136598]

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    descriptionThe SUSE Linux Enterprise 12 SP5 azure kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276). CVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424). CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629). CVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bnc#1165111). CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). CVE-2018-20836: Fixed an issue where a race condition in smp_task_timedout() and smp_task_done() could lead to a use-after-free (bnc#1134395). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

"The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2018-5390 aka 'SegmentSmack': A remote attacker even with
relatively low bandwidth could have caused lots of CPU usage by
triggering the worst case scenario during IP and/or TCP fragment
reassembly (bsc#1102340)

CVE-2018-7191: In the tun subsystem in the Linux kernel,
dev_get_valid_name was not called before register_netdevice. This
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. (bnc#1135603)

CVE-2018-20836: A race condition in smp_task_timedout() and
smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead
to a use-after-free. (bnc#1134395)

CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to
cause denial of service (a NULL pointer dereference and system crash).
(bnc#1137194)

CVE-2019-12818: The nfc_llcp_build_tlv function in
net/nfc/llcp_commands.c may have returned NULL. If the caller did not
check for this, it would trigger a NULL pointer dereference. This
would cause denial of service. (bnc#1138293)

CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
allowed local users to cause a denial of service or possibly have
unspecified other impact by changing the value of ioc_number between
two kernel reads of that value, aka a 'double fetch' vulnerability.
(bsc#1136922)

CVE-2019-11487: An attacker could have triggered use-after-free via
page reference count overflow on slow filesystems with at least of 140
GiB of RAM available. (bnc#1133190)

The update package also includes non-security fixes. See advisory for
details.

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    descriptionThe SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses (bnc#1140575 1140577). CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker

"The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2019-10638: In the Linux kernel, a device could be tracked by an
attacker using the IP ID values the kernel produces for
connection-less protocols (e.g., UDP and ICMP). When such traffic was
sent to multiple destination IP addresses, it was possible to obtain
hash collisions (of indices to the counter array) and thereby obtain
the hashing key (via enumeration). An attack may have been conducted
by hosting a crafted web page that uses WebRTC or gQUIC to force UDP
traffic to attacker-controlled IP addresses (bnc#1140575 1140577).

CVE-2019-10639: The Linux kernel allowed Information Exposure (partial
kernel address disclosure), leading to a KASLR bypass. Specifically,
it was possible to extract the KASLR kernel image offset using the IP
ID values the kernel produces for connection-less protocols (e.g., UDP
and ICMP). When such traffic was sent to multiple destination IP
addresses, it was possible to obtain hash collisions (of indices to
the counter array) and thereby obtain the hashing key (via
enumeration). This key contains enough bits from a kernel address (of
a static variable) so when the key was extracted (via enumeration),
the offset of the kernel image was exposed. This attack could be
carried out remotely, by the attacker forcing the target device to
send UDP or ICMP (or certain other) traffic to attacker-controlled IP
addresses. Forcing a server to send UDP traffic is trivial if the
server is a DNS server. ICMP traffic is trivial if the server answers
ICMP Echo requests (ping). For client targets, if the target visits
the attacker's web page, then WebRTC or gQUIC can be used to force UDP
traffic to attacker-controlled IP addresses. NOTE: this attack against
KASLR became viable because IP ID generation was changed to have a
dependency on an address associated with a network namespace
(bnc#1140577).

CVE-2019-13233: In arch/x86/lib/insn-eval.c in the Linux kernel, there
was a use-after-free for access to an LDT entry because of a race
condition between modify_ldt() and a #BR exception for an MPX bounds
violation (bnc#1140454).

CVE-2018-20836: An issue was discovered in the Linux kernel There was
a race condition in smp_task_timedout() and smp_task_done() in
drivers/scsi/libsas/sas_expander.c, leading to a use-after-free
(bnc#1134395).

CVE-2019-10126: A flaw was found in the Linux kernel. A heap based
buffer overflow in mwifiex_uap_parse_tail_ies function in
drivers/net/wireless/marvell/mwifiex/ie.c might have lead to memory
corruption and possibly other consequences (bnc#1136935).

CVE-2019-11599: The coredump implementation in the Linux kernel did
not use locking or other mechanisms to prevent vma layout or vma flags
changes while it ran, which allowed local users to obtain sensitive
information, cause a denial of service, or possibly have unspecified
other impact by triggering a race condition with mmget_not_zero or
get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c,
fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c
(bnc#1131645 1133738).

The update package also includes non-security fixes. See advisory for
details.

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836)The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.(CVE-2019-11190)The Siemens R3964 line discipline driver in drivers/tty_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)The Linux kernel before 5.1-rc5 allows page-i1/4z_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.(CVE-2019-11487)The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A n issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.(CVE-2019-11810)In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.(CVE-2018-7191)net/ipv6etfilterf_conntrac k_reasm.c in the Linux kernel before 2.6.34, when the nf_conntrack_ipv6 module is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.(CVE-2012-2744)Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.(CVE-2012-3400)The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive.(CVE-2013-2164)The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.(CVE-2013-6282)The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.(CVE-2013-2206)A elevation of privilege vulnerability in the Broadcom wi-fi driver. Product: Android. Versions: Android kernel. Android ID: A-37351060. References: B-V2017060101.(CVE-2017-0786)An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)Not e1: kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions in EulerOS Virtualization for ARM 64 3.0.2.0 return incorrect time information when executing the uname -a command.Note2: The kernel version number naming format has been changed after 4.19.36-1.2.184.aarch64, the new version format is 4.19.36-vhulk1907.1.0.hxxx.aarch64, which may lead to false positives of this security advisory. Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL familySuSE Local Security Checks
    NASL idSUSE_SU-2019-1852-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: In the Linux kernel, a device could be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses (bnc#1140575 1140577). CVE-2019-10639: The Linux kernel allowed Information Exposure (partial kernel address disclosure), that lead to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack could be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping).

    descriptionThe SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2020-8834: KVM on Power8 processors had a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability to run code in kernel space of a guest VM can cause the host kernel to panic (bnc#1168276). CVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424). CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629). CVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295). CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386). CVE-2019-19770: Fixed a use-after-free in the debugfs_remove function (bsc#1159198). CVE-2020-11669: Fixed an issue where arch/powerpc/kernel/idle_book3s.S did not have save/restore functionality for PNV_POWERSAVE_AMR, PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR (bnc#1169390). CVE-2020-2732: Fixed an issue where under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest (bnc#1163971). CVE-2020-8647: There was a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929 1164078). CVE-2020-8649: There was a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162929 1162931). CVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it (bnc#1165111).

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.(CVE-2012-3400)The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive.(CVE-2013-2164)The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.(CVE-2013-2206)The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.(CVE-2013-6282)An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836)The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.(CVE-2019-11487)The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A n issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.(CVE-2019-11810)An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A flaw was found in the Linux kernel

It is not clear how this might be exploited. - CVE-2019-1125 It was discovered that most x86 processors could speculatively skip a conditional SWAPGS instruction used when entering the kernel from user mode, and/or could speculatively execute it when it should be skipped. This is a subtype of Spectre variant 1, which could allow local users to obtain sensitive information from the kernel or other processes. It has been mitigated by using memory barriers to limit speculative execution. Systems using an i386 kernel are not affected as the kernel does not use SWAPGS. - CVE-2019-1999 A race condition was discovered in the Android binder driver, which could lead to a use-after-free.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-8553 Jan Beulich discovered that CVE-2015-2150 was not completely addressed. If a PCI physical function is passed through to a Xen guest, the guest is able to access its memory and I/O regions before enabling decoding of those regions. This could result in a denial-of-service (unexpected NMI) on the host. The fix for this is incompatible with qemu versions before 2.5. - CVE-2017-18509 Denis Andzakovic reported a missing type check in the IPv4 multicast routing implementation. A user with the CAP_NET_ADMIN capability (in any user namespace) could use this for denial-of-service (memory corruption or crash) or possibly for privilege escalation. - CVE-2018-5995 ADLab of VenusTech discovered that the kernel logged the virtual addresses assigned to per-CPU data, which could make it easier to exploit other vulnerabilities. - CVE-2018-20836 chenxiang reported a race condition in libsas, the kernel subsystem supporting Serial Attached SCSI (SAS) devices, which could lead to a use-after-free. It is not clear how this might be exploited. - CVE-2018-20856 Xiao Jin reported a potential double-free in the block subsystem, in case an error occurs while initialising the I/O scheduler for a block device. It is not clear how this might be exploited. - CVE-2019-1125 It was discovered that most x86 processors could speculatively skip a conditional SWAPGS instruction used when entering the kernel from user mode, and/or could speculatively execute it when it should be skipped. This is a subtype of Spectre variant 1, which could allow local users to obtain sensitive information from the kernel or other processes. It has been mitigated by using memory barriers to limit speculative execution. Systems using an i386 kernel are not affected as the kernel does not use SWAPGS. - CVE-2019-3882 It was found that the vfio implementation did not limit the number of DMA mappings to device memory. A local user granted ownership of a vfio device could use this to cause a denial of service (out-of-memory condition). - CVE-2019-3900 It was discovered that vhost drivers did not properly control the amount of work done to service requests from guest VMs. A malicious guest could use this to cause a denial-of-service (unbounded CPU usage) on the host. - CVE-2019-10207 The syzkaller tool found a potential null dereference in various drivers for UART-attached Bluetooth adapters.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A vulnerability was found in polkit. When authentication is performed by a non-root user to perform an administrative task, the authentication is temporarily cached in such a way that a local attacker could impersonate the authorized process, thus gaining access to elevated privileges.(CVE-2019-6133) - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs. As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged execve() calls.(CVE-2019-3901) - A race condition was found between between mmget_not_zero()/get_task_mm() when core dumping tasks. A local attacker is able to exploit race condition where locking of semaphore would allow an attacker to leak kernel memory to userspace.(CVE-2019-3892) - A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls.(CVE-2019-11599) - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836) - A flaw was found in the Linux kernel, prior to version 5.0.7, in drivers/scsi/megaraid/megaraid_sas_base.c, where a NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds(). An attacker can crash the system if they were able to load the megaraid_sas kernel module and groom memory beforehand, leading to a denial of service (DoS), related to a use-after-free.(CVE-2019-11810) - A flaw was found in the Linux kernel

    descriptionIt was discovered that a race condition existed in the Serial Attached SCSI (SAS) implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20836) It was discovered that the ext4 file system implementation in the Linux kernel did not properly zero out memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11833) It was discovered that the Bluetooth Human Interface Device Protocol (HIDP) implementation in the Linux kernel did not properly verify strings were NULL terminated in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11884) It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. (CVE-2019-2054) Hugues Anguelkov discovered that the Broadcom Wifi driver in the Linux kernel did not properly prevent remote firmware events from being processed for USB Wifi devices. A physically proximate attacker could use this to send firmware events to the device. (CVE-2019-9503) It was discovered that an integer overflow existed in the Freescale (PowerPC) hypervisor manager in the Linux kernel. A local attacker with write access to /dev/fsl-hv could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10142). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe SUSE Linux Enterprise 15 kernel version 4.12.14 was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575] CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-18509 Denis Andzakovic reported a missing type check in the IPv4 multicast routing implementation. A user with the CAP_NET_ADMIN capability (in any user namespace) could use this for denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2018-20836 chenxiang reported a race condition in libsas, the kernel subsystem supporting Serial Attached SCSI (SAS) devices, which could lead to a use-after-free. It is not clear how this might be exploited. CVE-2019-1125 It was discovered that most x86 processors could speculatively skip a conditional SWAPGS instruction used when entering the kernel from user mode, and/or could speculatively execute it when it should be skipped. This is a subtype of Spectre variant 1, which could allow local users to obtain sensitive information from the kernel or other processes. It has been mitigated by using memory barriers to limit speculative execution. Systems using an i386 kernel are not affected as the kernel does not use SWAPGS. CVE-2019-3900 It was discovered that vhost drivers did not properly control the amount of work done to service requests from guest VMs. A malicious guest could use this to cause a denial of service (unbounded CPU usage) on the host. CVE-2019-10207 The syzkaller tool found a potential null dereference in various drivers for UART-attached Bluetooth adapters.
