Ubuntu Security Notice USN-2370-1
October 08, 2014
apt vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS
Summary:
APT could be made to overwrite files.
Software Description:
– apt: Advanced front-end for dpkg
Details:
Guillem Jover discovered that APT incorrectly created a temporary file when
handling the changelog command. A local attacker could use this issue to
overwrite arbitrary files. In the default installation of Ubuntu, this
should be prevented by the kernel link restrictions.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS:
apt 1.0.1ubuntu2.5
Ubuntu 12.04 LTS:
apt 0.8.16~exp12ubuntu10.21
In general, a standard system update will make all the necessary changes.
