============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

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

Software Description:
- 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.
