========================================================================== Ubuntu Security Notice USN-3798-2 October 23, 2018
linux-lts-trusty vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM
Details:
USN-3798-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS.
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 12.04 ESM: linux-image-3.13.0-161-generic 3.13.0-161.211~precise1 linux-image-3.13.0-161-generic-lpae 3.13.0-161.211~precise1 linux-image-generic-lpae-lts-trusty 3.13.0.161.151 linux-image-generic-lts-trusty 3.13.0.161.151
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.
