Ubuntu Security Notice USN-2544-1
March 24, 2015

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 kernel.

Software Description:
- linux: Linux kernel

Details:

Eric Windisch discovered flaw in how the Linux kernel's XFS file system
replaces remote attributes. A local access with access to an XFS file
system could exploit this flaw to escalate their privileges.
(CVE-2015-0274)

A flaw was discovered in the automatic loading of modules in the crypto
subsystem of the Linux kernel. A local user could exploit this flaw to load
installed kernel modules, increasing the attack surface and potentially
using this to gain administrative privileges. (CVE-2013-7421)

The Linux kernel's splice system call did not correctly validate its
parameters. A local, unprivileged user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-7822)

A flaw was discovered in the crypto subsystem when screening module names
for automatic module loading if the name contained a valid crypto module
name, eg. vfat(aes). A local user could exploit this flaw to load installed
kernel modules, increasing the attack surface and potentially using this to
gain administrative privileges. (CVE-2014-9644)

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-48-generic   3.13.0-48.80
  linux-image-3.13.0-48-generic-lpae  3.13.0-48.80
  linux-image-3.13.0-48-lowlatency  3.13.0-48.80
  linux-image-3.13.0-48-powerpc-e500  3.13.0-48.80
  linux-image-3.13.0-48-powerpc-e500mc  3.13.0-48.80
  linux-image-3.13.0-48-powerpc-smp  3.13.0-48.80
  linux-image-3.13.0-48-powerpc64-emb  3.13.0-48.80
  linux-image-3.13.0-48-powerpc64-smp  3.13.0-48.80

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.
