Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description: - linux-lts-vivid: Linux hardware enablement kernel from Vivid for Trusty

Details:

Venkatesh Pottem discovered a use-after-free vulnerability in the Linux kernel's CXGB3 driver. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2015-8812)

Xiaofei Rex Guo discovered a timing side channel vulnerability in the Linux Extended Verification Module (EVM). An attacker could use this to affect system integrity. (CVE-2016-2085)

David Herrmann discovered that the Linux kernel incorrectly accounted file descriptors to the original opener for in-flight file descriptors sent over a unix domain socket. A local attacker could use this to cause a denial of service (resource exhaustion). (CVE-2016-2550)

It was discovered that the Linux kernel did not enforce limits on the amount of data allocated to buffer pipes. A local attacker could use this to cause a denial of service (resource exhaustion). (CVE-2016-2847)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
linux-image-3.19.0-58-generic 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-generic-lpae 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-lowlatency 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-powerpc-e500mc 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-powerpc-smp 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-powerpc64-emb 3.19.0-58.64~14.04.1
linux-image-3.19.0-58-powerpc64-smp 3.19.0-58.64~14.04.1

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.
