Debian DSA-3031-1 : apt - security update

medium Nessus Plugin ID 77824

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The Google Security Team discovered a buffer overflow vulnerability in the HTTP transport code in apt-get. An attacker able to man-in-the-middle a HTTP request to an apt repository can trigger the buffer overflow, leading to a crash of the 'http' apt method binary, or potentially to arbitrary code execution.

Two regression fixes were included in this update :

 - Fix regression from the previous update in DSA-3025-1 when the custom apt configuration option for Dir::state::lists is set to a relative path (#762160).
 - Fix regression in the reverification handling of cdrom:
 sources that may lead to incorrect hashsum warnings.
 Affected users need to run 'apt-cdrom add' again after the update was applied.

Solution

Upgrade the apt packages.

For the stable distribution (wheezy), this problem has been fixed in version 0.9.7.9+deb7u5.
