Debian DSA-2953-1 : dpkg - security update

Description

Multiple vulnerabilities were discovered in dpkg that allow file modification through path traversal when unpacking source packages with specially crafted patch files.

This update had been scheduled before the end of security support for the oldstable distribution (squeeze), hence an exception has been made and was released through the security archive. However, no further updates should be expected.
