USN-2901-1: xdelta3 vulnerability

17 February 2016

xdelta3 could be made to crash or run programs if it opened a specially crafted file.



  • xdelta3 - Diff utility which works with binary files


It was discovered that xdelta3 incorrectly handled certain files. If a user
or automated system were tricked into processing a specially-crafted file,
a remote attacker could use this issue to cause xdelta3 to crash, resulting
in 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 15.10
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
