Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : dpkg vulnerability (USN-2820-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Hanno Boeck discovered that the dpkg-deb tool incorrectly handled
certain old style Debian binary packages. If a user or an automated
system were tricked into unpacking a specially crafted binary package,
a remote attacker could possibly use this issue to execute arbitrary
code.

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 dpkg package.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
