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-utopic: Linux hardware enablement kernel from Utopic

Details:

Alexandre Oliva reported a race condition flaw in the btrfs file system's handling of extended attributes (xattrs). A local attacker could exploit this flaw to bypass ACLs and potentially escalate privileges. (CVE-2014-9710)

A memory corruption issue was discovered in AES decryption when using the Intel AES-NI accelerated code path. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate privileges on Intel base machines with AEC-GCM mode IPSec security association. (CVE-2015-3331)

A flaw was discovered in the Linux kernel's IPv4 networking when using TCP fast open to initiate a connection. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). (CVE-2015-3332)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.16.0-38-generic 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-generic-lpae 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-lowlatency 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-powerpc-e500mc 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-powerpc-smp 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-powerpc64-emb 3.16.0-38.52~14.04.1
linux-image-3.16.0-38-powerpc64-smp 3.16.0-38.52~14.04.1

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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
