Synopsis
========

Multiple vulnerabilities in libTIFF could lead to the execution of
arbitrary code or a Denial of Service.

Background
==========

libTIFF provides support for reading and manipulating TIFF images.

Affected packages
=================

-------------------------------------------------------------------

Description
===========

Multiple vulnerabilities, ranging from integer overflows and NULL
pointer dereferences to double frees, were reported in libTIFF.

Impact
======

An attacker could exploit these vulnerabilities by enticing a user to
open a specially crafted TIFF image, possibly leading to the execution
of arbitrary code or a Denial of Service.

Workaround
