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


Synopsis :

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

Description :

Mathias Krause discovered several errors in the Linux kernel's
xfrm_user implementation. A local attacker could exploit these flaws
to examine parts of kernel memory. (CVE-2012-6537)

Mathias Krause discovered information leak in the Linux kernel's
compat ioctl interface. A local user could exploit the flaw to examine
parts of kernel stack memory (CVE-2012-6539)

Mathias Krause discovered an information leak in the Linux kernel's
getsockopt for IP_VS_SO_GET_TIMEOUT. A local user could exploit this
flaw to examine parts of kernel stack memory. (CVE-2012-6540)

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

A memory use after free error was discover 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).

Solution :

Update the affected packages.
