USN-2726-1: Expat vulnerability
Ubuntu Security Notice USN-2726-1
31st August, 2015
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Expat could be made to crash or run programs as your login if it opened a specially crafted file.
- expat - XML parsing C library
It was discovered that Expat incorrectly handled malformed XML data. If a
user or application linked against Expat were tricked into opening a
crafted XML file, an attacker could cause a denial of service, or possibly
execute arbitrary code.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 15.04:
- libexpat1 2.1.0-6ubuntu1.1
- lib64expat1 2.1.0-6ubuntu1.1
- Ubuntu 14.04 LTS:
- libexpat1 2.1.0-4ubuntu1.1
- lib64expat1 2.1.0-4ubuntu1.1
- Ubuntu 12.04 LTS:
- libexpat1 2.0.1-7.2ubuntu1.2
- lib64expat1 2.0.1-7.2ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart any applications linked
against Expat to effect the necessary changes.
