HIGH Summary
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.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1527-1.NASL description The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586) CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. CVE-2019-11479: It was possible to send a crafted sequence of SACKs which will fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values. CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424) CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel There was an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586) CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843). CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281) CVE-2018-7191: In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is 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. This is similar to CVE-2013-4343. (bnc#1135603) CVE-2019-11190: The Linux kernel allowed 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. (bnc#1131543) CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537) CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a last seen 2020-06-01 modified 2020-06-02 plugin id 125990 published 2019-06-18 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125990 title SUSE SLES12 Security Update : kernel (SUSE-SU-2019:1527-1) (SACK Panic) (SACK Slowness) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from SUSE update advisory SUSE-SU-2019:1527-1. # The text itself is copyright (C) SUSE. # include("compat.inc"); if (description) { script_id(125990); script_version("1.4"); script_cvs_date("Date: 2020/01/10"); script_cve_id("CVE-2013-4343", "CVE-2018-17972", "CVE-2018-7191", "CVE-2019-11190", "CVE-2019-11477", "CVE-2019-11478", "CVE-2019-11479", "CVE-2019-11486", "CVE-2019-11815", "CVE-2019-11833", "CVE-2019-11884", "CVE-2019-12382", "CVE-2019-3846", "CVE-2019-5489"); script_bugtraq_id(62360); script_name(english:"SUSE SLES12 Security Update : kernel (SUSE-SU-2019:1527-1) (SACK Panic) (SACK Slowness)"); script_summary(english:"Checks rpm output for the updated packages."); script_set_attribute( attribute:"synopsis", value:"The remote SUSE host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1532-1.NASL description The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data. Further, it would consume additional resources such as CPU and NIC processing power. CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424) CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel, there was an unchecked kstrdup of fwstr, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586) CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may have been possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server. (bnc#1120843) CVE-2019-11833: fs/ext4/extents.c in the Linux kernel did not zero out the unused memory region in the extent tree block, which might have allowed local users to obtain sensitive information by reading uninitialized data in the filesystem. (bnc#1135281) 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-2019-11190: The Linux kernel allowed local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() was called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check had a race condition when reading /proc/pid/stat. (bnc#1132472) CVE-2019-11815: An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel There was a race condition leading to a use-after-free, related to net namespace cleanup. (bnc#1134537) CVE-2019-11884: The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel allowed a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a last seen 2020-06-01 modified 2020-06-02 plugin id 125993 published 2019-06-18 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125993 title SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2019:1532-1) (SACK Panic) (SACK Slowness) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from SUSE update advisory SUSE-SU-2019:1532-1. # The text itself is copyright (C) SUSE. # include("compat.inc"); if (description) { script_id(125993); script_version("1.4"); script_cvs_date("Date: 2020/01/10"); script_cve_id("CVE-2018-17972", "CVE-2018-7191", "CVE-2019-11190", "CVE-2019-11477", "CVE-2019-11478", "CVE-2019-11479", "CVE-2019-11486", "CVE-2019-11815", "CVE-2019-11833", "CVE-2019-11884", "CVE-2019-12382", "CVE-2019-3846", "CVE-2019-5489"); script_name(english:"SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2019:1532-1) (SACK Panic) (SACK Slowness)"); script_summary(english:"Checks rpm output for the updated packages."); script_set_attribute( attribute:"synopsis", value:"The remote SUSE host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.180 to receive various security and bugfixes.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1529-1.NASL description The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data. Further, it would consume additional resources such as CPU and NIC processing power. CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424) CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel, there was an unchecked kstrdup of fwstr, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586) CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.)

The following security bugs were fixed : CVE-2019-11477: A sequence of SACKs may have been crafted such that one can trigger an integer overflow, leading to a kernel panic. CVE-2019-11478: It was possible to send a crafted sequence of SACKs which will fragment the TCP retransmission queue. An attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. CVE-2019-11479: An attacker could force the Linux kernel to segment its responses into multiple TCP segments. This would drastically increased the bandwidth required to deliver the same amount of data. Further, it would consume additional resources such as CPU and NIC processing power. CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (bnc#1136424) CVE-2019-12382: An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel, there was an unchecked kstrdup of fwstr, which might have allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). (bnc#1136586) CVE-2019-5489: The mincore() implementation in mm/mincore.c in the Linux kernel allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.)

NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1635.NASL description According 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. last seen 2020-05-13 modified 2019-05-30 plugin id 125587 published 2019-05-30 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125587 title EulerOS Virtualization for ARM 64 3.0.2.0 : kernel (EulerOS-SA-2019-1635) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2019-4710.NASL description Description of changes: [4.1.12-124.28.6.el7uek] - scsi: libfc: Fixup disc_mutex handling in fcoe module (Hannes Reinecke) [Orabug: 29511036] - scsi: libfc: sanitize E_D_TOV and R_A_TOV setting in fcp (Hannes Reinecke) [Orabug: 29511036] - sysctl: Fix kabi breakage (Shuning Zhang) [Orabug: 29689925] - proc: Fix proc_sys_prune_dcache to hold a sb reference (Eric W.

The following security bugs were fixed : - CVE-2019-11477: A sequence of SACKs may have been crafted by a remote attacker such that one can trigger an integer overflow, leading to a kernel panic. (bsc#1137586). - CVE-2019-11478: It was possible to send a crafted sequence of SACKs which would fragment the TCP retransmission queue. A remote attacker may have been able to further exploit the fragmented queue to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. (bsc#1137586) - CVE-2019-11479: It was possible to send a crafted sequence of SACKs which would fragment the RACK send map. A remote attacker may be able to further exploit the fragmented send map to cause an expensive linked-list walk for subsequent SACKs received for that same TCP connection. This would have resulted in excess resource consumption due to low mss values. (bsc#1137586) - CVE-2019-12819: The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free.

There is a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c.(CVE-2019-15921) - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service.(CVE-2019-15807) - An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.(CVE-2019-15538) - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel last seen 2020-03-26 modified 2020-03-20 plugin id 134735 published 2020-03-20 reporter This script is Copyright (C) 2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/134735 title EulerOS Virtualization 3.0.2.2 : kernel (EulerOS-SA-2020-1269) NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-2430-1.NASL description The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bugfixes.
