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

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 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

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.

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 : 4.3
CVSS Temporal Score : 3.2
Public Exploit Available : false
