Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : apt vulnerability (USN-2353-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that APT incorrectly handled certain http URLs. If a
remote attacker were able to perform a man-in-the-middle attack, this
flaw could be exploited to cause APT to crash, resulting in a denial
of service, or possibly execute arbitrary code. The default compiler
options for affected releases should reduce the vulnerability to a
denial of service. (CVE-2014-6273)

In addition, this update fixes regressions introduced by the
USN-2348-1 security update: APT incorrectly handled file:/// sources
on a different partition, incorrectly handled Dir::state::lists set to
a relative path, and incorrectly handled cdrom: sources.

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 apt package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:F/RL:OF/RC:ND)
Public Exploit Available : true
