Synopsis
========
A vulnerability in Pngcrush might result in user-assisted execution of
arbitrary code.
Background
==========
Pngcrush is a multi platform optimizer for PNG (Portable Network
Graphics) files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/pngcrush < 1.6.4-r1 >= 1.6.4-r1
Description
===========
It has been reported that Pngcrush includes a copy of libpng that is
vulnerable to a memory corruption (GLSA 200804-15).
Impact
======
A remote attacker could entice a user to process a specially crafted
PNG image, possibly resulting in the execution of arbitrary code with
the privileges of the user running the application, or a Denial of
Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Pngcrush users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/pngcrush-1.6.4-r1"
