Ubuntu 9.10 / 10.04 LTS / 10.10 : dpkg vulnerability (USN-1038-1)

Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Jakub Wilk and Raphael Hertzog discovered that dpkg-source did not
correctly handle certain paths and symlinks when unpacking
source-format version 3.0 packages. If a user or an automated system
were tricked into unpacking a specially crafted source package, a
remote attacker could modify files outside the target unpack
directory, leading to a denial of service or potentially gaining
access to the system.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
