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

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

– Ubuntu 16.10
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS

Summary:

The GD library could be made to crash or run programs if it processed a
specially crafted image file.

Software Description:
– libgd2: GD Graphics Library

Details:

Ibrahim El-Sayed discovered that the GD library incorrectly handled certain
malformed Tiff images. If a user or automated system were tricked into
processing a specially crafted Tiff image, an attacker could cause a denial
of service. (CVE-2016-6911)

Ke Liu discovered that the GD library incorrectly handled certain integers
when processing WebP images. If a user or automated system were tricked
into processing a specially crafted WebP image, an attacker could cause a
denial of service, or possibly execute arbitrary code. This issue only
applied to Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.
(CVE-2016-7568)

Emmanuel Law discovered that the GD library incorrectly handled certain
strings when creating images. If a user or automated system were tricked

of service, or possibly execute arbitrary code. (CVE-2016-8670)
