Description Martin Prpič 2015-11-27 08:57:25 UTC 
Debian fixed the following flaw in dpkg:

Hanno Boeck discovered a stack-based buffer overflow in the dpkg-deb component of dpkg, the Debian package management system. This flaw could potentially lead to arbitrary code execution if a user or an automated system were tricked into processing a specially crafted Debian binary package (.deb) in the old style Debian binary package format.

These look like the correct patches:

https://anonscm.debian.org/cgit/dpkg/dpkg.git/commit/?h=wheezy&id=f1aac7d933819569bf6f347c3c0d5a64a90bbce0

Though, strictly speaking, only the first patch is related to CVE-2015-0860. The other two are mentioned in the oss-sec mail I linked to but don't have CVEs; I'm assuming they don't have any security implications and are classed as regular bugs.
