Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : linux, linux-source-2.6.15 vulnerability (USN-819-1)

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Tavis Ormandy and Julien Tinnes discovered that Linux did not
correctly initialize certain socket operation function pointers. A
local attacker could exploit this to gain root privileges. By default,
Ubuntu 8.04 and later with a non-zero /proc/sys/vm/mmap_min_addr
setting were not vulnerable.

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 :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.6
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
