All supported architectures
gif2png contains a stack overflow vulnerability when parsing command line
gif2png is a command line program that converts image files from the
Graphics Interchange Format (GIF) format to the Portable Network
Graphics (PNG) format.
gif2png contains a command line parsing vulnerability that may result
in a stack overflow due to an unexpectedly long input filename.
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.
There is no known workaround at this time.
All gif2png users should upgrade to the latest stable version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.1-r1"
