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

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 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.

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 :

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