Synopsis
========
gif2png contains a stack overflow vulnerability when parsing command
line arguments.
Background
==========
gif2png is a command line program that converts image files from the
Graphics Interchange Format (GIF) format to the Portable Network
Graphics (PNG) format.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/gif2png < 2.5.1-r1 >= 2.5.1-r1
Description
===========
gif2png contains a command line parsing vulnerability that may result
in a stack overflow due to an unexpectedly long input filename.
Impact
======
A remote attacker could entice a user to open a specially crafted
image, possibly resulting in the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
Note that applications relying on gif2png to process images can also
trigger the vulnerability.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All gif2png users should upgrade to the latest stable version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.1-r1"
References
==========
[ 1 ] CVE-2009-5018
