USN-2726-1: Expat vulnerability

31 August 2015

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04

After a standard system upgrade you need to restart any applications linked
against Expat to effect the necessary changes.
