Multiple vulnerabilities have been found in gif2png, the worst of which might allow execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/gif2png | * | < 2.5.8 | >= 2.5.8 |
gif2png converts images from GIF format to PNG format.
Two vulnerabilities have been found in gif2png:
A remote attacker could entice a user to open a specially crafted GIF file, possibly resulting in execution of arbitrary code, a Denial of Service condition, or the creation of PNG files in unintended directories.
There is no known workaround at this time.
All gif2png users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.8"
gif2png contains a stack overflow vulnerability when parsing command line arguments.
| Package | Arch | Vulnerable | Unaffected |

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:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/gif2png-2.5.1-r1"
