Ubuntu Security Notice 2616-1 - 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. 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. Various other issues were also addressed.

linux vulnerabilities
============================================================================

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

- Ubuntu 14.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

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 14.10:
linux-image-3.16.0-38-generic 3.16.0-38.52
linux-image-3.16.0-38-generic-lpae 3.16.0-38.52
linux-image-3.16.0-38-lowlatency 3.16.0-38.52
linux-image-3.16.0-38-powerpc-e500mc 3.16.0-38.52
linux-image-3.16.0-38-powerpc-smp 3.16.0-38.52
linux-image-3.16.0-38-powerpc64-emb 3.16.0-38.52
linux-image-3.16.0-38-powerpc64-smp 3.16.0-38.52

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.
