Ubuntu 10.04 LTS : linux-lts-backport-oneiric vulnerabilities (USN-1788-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Emese Revfy discovered that in the Linux kernel signal handlers could
leak address information across an exec, making it possible to bypass
ASLR (Address Space Layout Randomization). A local user could use this
flaw to bypass ASLR to reliably deliver an exploit payload that would
otherwise be stopped (by ASLR). (CVE-2013-0914)

A memory use after free error was discovered in the Linux kernel's
tmpfs filesystem. A local user could exploit this flaw to gain
privileges or cause a denial of service (system crash).
(CVE-2013-1767)

Mateusz Guzik discovered a race in the Linux kernel's keyring. A local
user could exploit this flaw to cause a denial of service (system
crash). (CVE-2013-1792).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.
