Ubuntu 11.10 / 12.04 LTS / 12.10 : apt vulnerability (USN-1762-1)

Ubuntu Security Notice (C) 2013-2014 Canonical, Inc. / NASL script (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Ansgar Burchardt discovered that APT incorrectly handled InRelease
files. If a remote attacker were able to perform a man-in-the-middle
attack, this flaw could potentially be used to install altered
packages.

This update corrects the issue by disabling InRelease file support
completely. Please note that this update breaks third-party
repositories that provide only a InRelease file and no separate
Release and Release.gpg files. The default Ubuntu repositories do not
use InRelease files.

Solution :

Update the affected apt package.

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
