========================================================================== Ubuntu Security Notice USN-3445-2 October 11, 2017
linux 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: Linux kernel
Details:
USN-3445-1 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 ESM.
Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges. (CVE-2016-8633)
Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14106)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 ESM: linux-image-3.2.0-131-generic 3.2.0-131.177 linux-image-3.2.0-131-generic-pae 3.2.0-131.177 linux-image-3.2.0-131-highbank 3.2.0-131.177 linux-image-3.2.0-131-omap 3.2.0-131.177 linux-image-3.2.0-131-powerpc-smp 3.2.0-131.177 linux-image-3.2.0-131-powerpc64-smp 3.2.0-131.177 linux-image-3.2.0-131-virtual 3.2.0-131.177 linux-image-generic 3.2.0.131.145 linux-image-generic-pae 3.2.0.131.145 linux-image-highbank 3.2.0.131.145 linux-image-omap 3.2.0.131.145 linux-image-powerpc-smp 3.2.0.131.145 linux-image-powerpc64-smp 3.2.0.131.145
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.
