"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - A flaw was found in the Linux kernel's implementation
    of GRO. This flaw allows an attacker with local access
    to crash the system.(CVE-2020-10720)

  - A NULL pointer dereference flaw was found in the Linux
    kernel's SELinux subsystem. This flaw occurs while
    importing the Commercial IP Security Option (CIPSO)
    protocol's category bitmap into the SELinux extensible
    bitmap via the' ebitmap_netlbl_import' routine. While
    processing the CIPSO restricted bitmap tag in the
    'cipso_v4_parsetag_rbm' routine, it sets the security
    attribute to indicate that the category bitmap is
    present, even if it has not been allocated. This issue
    leads to a NULL pointer dereference issue while
    importing the same category bitmap into SELinux. This
    flaw allows a remote network user to crash the system
    kernel, resulting in a denial of
    service.(CVE-2020-10711)

  - A signal access-control issue was discovered in the
    Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32
    bits, an integer overflow can interfere with a
    do_notify_parent protection mechanism. A child process
    can send an arbitrary signal to a parent process in a
    different security domain. Exploitation limitations
    include the amount of elapsed time before an integer
    overflow occurs, and the lack of scenarios where
    signals to a parent process present a substantial
    operational threat.(CVE-2020-12826)

  - An issue was discovered in the Linux kernel before
    5.4.17. drivers/spi/spi-dw.c allows attackers to cause
    a panic via concurrent calls to dw_spi_irq and
    dw_spi_transfer_one, aka
    CID-19b61392c5a8.(CVE-2020-12769)

  - An issue was discovered in the Linux kernel through
    5.6.11. sg_write lacks an sg_remove_request call in a
    certain failure case, aka
    CID-83c6f2390040.(CVE-2020-12770)

  - An issue was discovered in the Linux kernel through
    5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c
    has a deadlock if a coalescing operation
    fails.(CVE-2020-12771)

  - The __mptctl_ioctl function in
    drivers/message/fusion/mptctl.c in the Linux kernel
    before 5.4.14 allows local users to hold an incorrect
    lock during the ioctl operation and trigger a race
    condition, i.e., a 'double fetch' vulnerability, aka
    CID-28d76df18f0a. NOTE: the vendor states 'The security
    impact of this bug is not as bad as it could have been
    because these operations are all privileged and root
    already has enormous destructive
    power.'(CVE-2020-12652)

  - An issue was discovered in xfs_agf_verify in
    fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through
    5.6.10. Attackers may trigger a sync of excessive
    duration via an XFS v5 image with crafted metadata, aka
    CID-d0c7feaf8767.(CVE-2020-12655)

  - A pivot_root race condition in fs amespace.c in the
    Linux kernel 4.4.x before 4.4.221, 4.9.x before
    4.9.221, 4.14.x before 4.14.178, 4.19.x before
    4.19.119, and 5.x before 5.3 allows local users to
    cause a denial of service (panic) by corrupting a
    mountpoint reference counter.(CVE-2020-12114)

  - An issue was discovered in the Linux kernel before
    5.6.5. There is a use-after-free in block/bfq-iosched.c
    related to bfq_idle_slice_timer_body.(CVE-2020-12657)

  - usb_sg_cancel in drivers/usb/core/message.c in the
    Linux kernel before 5.6.8 has a use-after-free because
    a transfer occurs without a reference, aka
    CID-056ad39ee925.(CVE-2020-12464)

  - An issue was found in Linux kernel before 5.5.4. The
    mwifiex_cmd_append_vsie_tlv() function in drivers
    et/wireless/marvell/mwifiex/scan.c allows local users
    to gain privileges or cause a denial of service because
    of an incorrect memcpy and buffer overflow, aka
    CID-b70261a288ea.(CVE-2020-12653)

  - gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c
    in the rpcsec_gss_krb5 implementation in the Linux
    kernel through 5.6.10 lacks certain domain_release
    calls, leading to a memory leak.(CVE-2020-12656)

  - An issue was discovered in the Linux kernel before
    5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an
    out-of-bounds write (by a user with the CAP_NET_ADMIN
    capability) because of a lack of headroom
    validation.(CVE-2020-12659)

  - An array overflow was discovered in mt76_add_fragment
    in drivers et/wireless/mediatek/mt76/dma.c in the Linux
    kernel before 5.5.10, aka CID-b102f0c522cf. An
    oversized packet with too many rx fragments can corrupt
    memory of adjacent pages.(CVE-2020-12465)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in drivers
    et/wireless/marvell/mwifiex/wmm.c allows a remote AP to
    trigger a heap-based buffer overflow because of an
    incorrect memcpy, aka CID-3a9b153c5591.(CVE-2020-12654)

  - In the Linux kernel through 5.6.7 on the s390 platform,
    code execution may occur because of a race condition,
    as demonstrated by code in enable_sacf_uaccess in
    arch/s390/lib/uaccess.c that fails to protect against a
    concurrent page table upgrade, aka CID-3f777e19d171. A
    crash could also occur.(CVE-2020-11884)

  - relay_open in kernel/relay.c in the Linux kernel
    through 5.4.1 allows local users to cause a denial of
    service (such as relay blockage) by triggering a NULL
    alloc_percpu result.(CVE-2019-19462)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs
    filesystem image, performing some operations, and
    unmounting can lead to a use-after-free in
    btrfs_queue_work in
    fs/btrfs/async-thread.c.(CVE-2019-19377)

  - In the Linux kernel before 5.5.8, get_raw_socket in
    drivers/vhost et.c lacks validation of an sk_family
    field, which might allow attackers to trigger kernel
    stack corruption via crafted system
    calls.(CVE-2020-10942)

    NASL idSUSE_SU-2020-1275-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : 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-2020-8647: Fixed a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: Fixed a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c, which leads to a wait_til_ready out-of-bounds read (bnc#1165111). 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-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). CVE-2020-11609: Fixed a NULL pointer dereference in the stv06xx subsystem caused by mishandling invalid descriptors (bnc#1168854). CVE-2020-10720: Fixed a use-after-free read in napi_gro_frags() (bsc#1170778). CVE-2020-10690: Fixed the race between the release of ptp_clock and cdev (bsc#1170056). CVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a video driver. This could lead to local information disclosure with System execution privileges needed (bnc#1170345). CVE-2020-11608: Fixed an issue in drivers/media/usb/gspca/ov519.c caused by a NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints (bnc#1168829). CVE-2017-18255: The perf_cpu_time_max_percent_handler function in kernel/events/core.c allowed local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation (bnc#1087813). CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928). CVE-2020-2732: A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. 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-2019-5108: Fixed a denial-of-service vulnerability caused by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912). CVE-2020-8992: ext4_protect_reserved_inode in fs/ext4/block_validity.c allowed attackers to cause a denial of service (soft lockup) via a crafted journal size (bnc#1164069). CVE-2018-21008: Fixed a use-after-free which could be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591). CVE-2019-14896: A heap-based buffer overflow vulnerability was found in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (bnc#1157157). CVE-2019-14897: A stack-based buffer overflow was found in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA (bnc#1157155). CVE-2019-18675: Fixed an integer overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allowed local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation (bnc#1157804). CVE-2019-14615: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may have allowed an unauthenticated user to potentially enable information disclosure via local access (bnc#1160195, bsc#1165881). CVE-2019-19965: Fixed a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bnc#1159911). CVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links (bnc#1159910). CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bnc#1159908). CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841). CVE-2019-19447: Fixed an issue with mounting a crafted ext4 filesystem image, performing some operations, and unmounting could lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c (bnc#1158819). CVE-2019-19319: Fixed an issue with a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021). CVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297).

"The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

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-2020-8647: Fixed a use-after-free vulnerability in the
vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).

CVE-2020-8649: Fixed a use-after-free vulnerability in the
vgacon_invert_region function in drivers/video/console/vgacon.c
(bnc#1162931).

CVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c,
which leads to a wait_til_ready out-of-bounds read (bnc#1165111).

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-2019-19768: Fixed a use-after-free in the __blk_add_trace function
in kernel/trace/blktrace.c (bnc#1159285).

CVE-2020-11609: Fixed a NULL pointer dereference in the stv06xx
subsystem caused by mishandling invalid descriptors (bnc#1168854).

CVE-2020-10720: Fixed a use-after-free read in napi_gro_frags()
(bsc#1170778).

CVE-2020-10690: Fixed the race between the release of ptp_clock and
cdev (bsc#1170056).

CVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a
video driver. This could lead to local information disclosure with
System execution privileges needed (bnc#1170345).

CVE-2020-11608: Fixed an issue in drivers/media/usb/gspca/ov519.c
caused by a NULL pointer dereferences in ov511_mode_init_regs and
ov518_mode_init_regs when there are zero endpoints (bnc#1168829).

CVE-2017-18255: The perf_cpu_time_max_percent_handler function in
kernel/events/core.c allowed local users to cause a denial of service
(integer overflow) or possibly have unspecified other impact via a
large value, as demonstrated by an incorrect sample-rate calculation
(bnc#1087813).

CVE-2020-8648: There was a use-after-free vulnerability in the
n_tty_receive_buf_common function in drivers/tty/n_tty.c
(bnc#1162928).

CVE-2020-2732: A flaw was discovered in the way that the KVM
hypervisor handled instruction emulation for an L2 guest when nested
virtualisation is enabled. 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-2019-5108: Fixed a denial-of-service vulnerability caused by
triggering AP to send IAPP location updates for stations before the
required authentication process has completed (bnc#1159912).

CVE-2020-8992: ext4_protect_reserved_inode in fs/ext4/block_validity.c
allowed attackers to cause a denial of service (soft lockup) via a
crafted journal size (bnc#1164069).

CVE-2018-21008: Fixed a use-after-free which could be caused by the
function rsi_mac80211_detach in the file
drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).

CVE-2019-14896: A heap-based buffer overflow vulnerability was found
in Marvell WiFi chip driver. A remote attacker could cause a denial of
service (system crash) or, possibly execute arbitrary code, when the
lbs_ibss_join_existing function is called after a STA connects to an
AP (bnc#1157157).

CVE-2019-14897: A stack-based buffer overflow was found in Marvell
WiFi chip driver. An attacker is able to cause a denial of service
(system crash) or, possibly execute arbitrary code, when a STA works
in IBSS mode (allows connecting stations together without the use of
an AP) and connects to another STA (bnc#1157155).

CVE-2019-18675: Fixed an integer overflow in cpia2_remap_buffer in
drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap
implementation. This allowed local users (with /dev/video0 access) to
obtain read and write permissions on kernel physical pages, which can
possibly result in a privilege escalation (bnc#1157804).

CVE-2019-14615: Insufficient control flow in certain data structures
for some Intel(R) Processors with Intel(R) Processor Graphics may have
allowed an unauthenticated user to potentially enable information
disclosure via local access (bnc#1160195, bsc#1165881).

CVE-2019-19965: Fixed a NULL pointer dereference in
drivers/scsi/libsas/sas_discover.c because of mishandling of port
disconnection during discovery, related to a PHY down race condition
(bnc#1159911).

CVE-2019-20054: Fixed a NULL pointer dereference in
drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links
(bnc#1159910).

CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in
net/dccp/feat.c, which may cause denial of service (bnc#1159908).

CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in
drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service
(bnc#1159841).

CVE-2019-19447: Fixed an issue with mounting a crafted ext4 filesystem
image, performing some operations, and unmounting could lead to a
use-after-free in ext4_put_super in fs/ext4/super.c, related to
dump_orphan_list in fs/ext4/super.c (bnc#1158819).

CVE-2019-19319: Fixed an issue with a setxattr operation, after a
mount of a crafted ext4 image, can cause a slab-out-of-bounds write
access because of an ext4_xattr_set_entry use-after-free in
fs/ext4/xattr.c when a large old_size value is used in a memset call
(bnc#1158021).

CVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as
demonstrated by use-after-free errors in __ext4_expand_extra_isize and
ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c
(bnc#1159297).

CVE-2019-11091,CVE-2018-12126,CVE-2018-12130,CVE-2018-12127: Earlier
mitigations for the 'MDS' Microarchitectural Data Sampling attacks
were not complete. An additional fix was added to the x86_64 fast
systemcall path to further mitigate these attacks. (bsc#1164846
bsc#1170847)

    NASL idSUSE_SU-2020-1255-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : 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-2020-8647: Fixed a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929). CVE-2020-8649: Fixed a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931). CVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c, which leads to a wait_til_ready out-of-bounds read (bnc#1165111). 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-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285). CVE-2020-11609: Fixed a NULL pointer dereference in the stv06xx subsystem caused by mishandling invalid descriptors (bnc#1168854). CVE-2020-10720: Fixed a use-after-free read in napi_gro_frags() (bsc#1170778). CVE-2020-10690: Fixed the race between the release of ptp_clock and cdev (bsc#1170056). CVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a video driver. This could lead to local information disclosure with System execution privileges needed (bnc#1170345). CVE-2020-11608: Fixed an issue in drivers/media/usb/gspca/ov519.c caused by a NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints (bnc#1168829). CVE-2017-18255: The perf_cpu_time_max_percent_handler function in kernel/events/core.c allowed local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation (bnc#1087813). CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928). CVE-2020-2732: A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. 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-2019-5108: Fixed a denial-of-service vulnerability caused by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912). CVE-2020-8992: ext4_protect_reserved_inode in fs/ext4/block_validity.c allowed attackers to cause a denial of service (soft lockup) via a crafted journal size (bnc#1164069). CVE-2018-21008: Fixed a use-after-free which could be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591). CVE-2019-14896: A heap-based buffer overflow vulnerability was found in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP (bnc#1157157). CVE-2019-14897: A stack-based buffer overflow was found in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA (bnc#1157155). CVE-2019-18675: Fixed an integer overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allowed local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation (bnc#1157804). CVE-2019-14615: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may have allowed an unauthenticated user to potentially enable information disclosure via local access (bnc#1160195, bsc#1165881). CVE-2019-19965: Fixed a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bnc#1159911). CVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links (bnc#1159910). CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bnc#1159908). CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841). CVE-2019-19447: Fixed an issue with mounting a crafted ext4 filesystem image, performing some operations, and unmounting could lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c (bnc#1158819). CVE-2019-19319: Fixed an issue with a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021). CVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297). CVE-2019-19066: Fixed memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c that allowed attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures (bnc#1157303).
