USN-2901-1: xdelta3 vulnerability

Releases

• Ubuntu 15.10
• Ubuntu 14.04 ESM

Packages

• xdelta3 - Diff utility which works with binary files

Details

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

• xdelta3 - 3.0.8-dfsg-1ubuntu0.15.10.2

Ubuntu 14.04

• xdelta3 - 3.0.7-dfsg-2ubuntu0.2

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