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"
