Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : dpkg vulnerability (USN-2566-1)

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


Synopsis :

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

Description :

Jann Horn discovered that dpkg incorrectly validated signatures when
extracting local source packages. If a user or an automated system
were tricked into unpacking a specially crafted source package, a
remote attacker could bypass signature verification checks.

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-dev and / or libdpkg-perl packages.

Risk factor :

Medium / CVSS Base Score : 4.3
(CVSS2#AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVSS Temporal Score : 3.2
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
