USN-2820-1: dpkg vulnerability
Ubuntu Security Notice USN-2820-1
26th November, 2015
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
dpkg-deb could be made to crash or run programs as your login if it opened a specially crafted file.
- dpkg - Debian package management system
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 15.10:
- dpkg 1.18.2ubuntu5.1
- Ubuntu 15.04:
- dpkg 1.17.25ubuntu1.1
- Ubuntu 14.04 LTS:
- dpkg 1.17.5ubuntu5.5
- Ubuntu 12.04 LTS:
- dpkg 220.127.116.11ubuntu7.7
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
