========================================================================== Ubuntu Security Notice USN-3798-1 October 23, 2018
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel
Details:
Dmitry Vyukov discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is negatively instantiated. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2015-8539)
It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913)
Pengfei Ding (äžé¹é£), Chenfu Bao (å
æ²æµ®), and Lenx Wei (éŠé¬) discovered a race condition in the generic SCSI driver (sg) of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-0794)
Eric Biggers discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is uninstantiated. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15299)
It was discovered that a NULL pointer dereference could be triggered in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18216)
Luo Quan and Wei Yang discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system deadlock). (CVE-2018-1000004)
èéŸé£ discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to a use- after-free or an out-of-bounds buffer access. A local attacker with access to /dev/snd/seq could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-7566)
It was discovered that a buffer overflow existed in the NFC Logical Link Control Protocol (llcp) implementation in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9518)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-161-generic 3.13.0-161.211 linux-image-3.13.0-161-generic-lpae 3.13.0-161.211 linux-image-3.13.0-161-lowlatency 3.13.0-161.211 linux-image-3.13.0-161-powerpc-e500 3.13.0-161.211 linux-image-3.13.0-161-powerpc-e500mc 3.13.0-161.211 linux-image-3.13.0-161-powerpc-smp 3.13.0-161.211 linux-image-3.13.0-161-powerpc64-emb 3.13.0-161.211 linux-image-3.13.0-161-powerpc64-smp 3.13.0-161.211 linux-image-generic 3.13.0.161.171 linux-image-generic-lpae 3.13.0.161.171 linux-image-highbank 3.13.0.161.171 linux-image-lowlatency 3.13.0.161.171 linux-image-powerpc-e500 3.13.0.161.171 linux-image-powerpc-e500mc 3.13.0.161.171 linux-image-powerpc-smp 3.13.0.161.171 linux-image-powerpc64-emb 3.13.0.161.171 linux-image-powerpc64-smp 3.13.0.161.171
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
