libwebp vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)
Summary:
libwebp could be made to crash or run programs as your login if it opened a
specially crafted file.
Software Description:
- libwebp: Lossy compression of digital photographic images.
Details:
USN-6078-1 fixed a vulnerability in libwebp. This update
provides the corresponding update for Ubuntu 16.04 LTS.
Original advisory details:
Irvan Kurniawan discovered that libwebp incorrectly handled certain memory
operations. If a user or automated system were tricked into opening a
specially crafted image file, a remote attacker could use this issue to
cause libwebp to crash, resulting in a denial of service, or possibly
execute arbitrary code.
