Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

A Denial of Service vulnerability was detected in the stack segment
fault handler. A local attacker could exploit this by causing stack
fault exceptions under special circumstances (scheduling), which lead
to a kernel crash. (CAN-2005-1767)

Vasiliy Averin discovered a Denial of Service vulnerability in the
'tiocgdev' ioctl call and in the 'routing_ioctl' function. By calling
fget() and fput() in special ways, a local attacker could exploit this
to destroy file descriptor structures and crash the kernel.
(CAN-2005-3044).

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.

Risk factor :

Low / CVSS Base Score : 2.1
