dpkg vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10

Summary
dpkg-deb could be made to crash or run programs as your login if it opened a specially crafted file.
Software description

Details
Hanno Boeck discovered that the dpkg-deb tool incorrectly handled certain
old style Debian binary packages. If a user or an automated system were
tricked into unpacking a specially crafted binary package, a remote
attacker could possibly use this issue to execute arbitrary code.
