AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions gif2png versions 2.5.3 and earlier

Description A buffer overflow issue exists in the gif2png.c file of gif2png, potentially allowing attackers to cause a denial of service (application crash) or have other unspecified impacts. This can occur when processing a GIF file containing many images, resulting in long extensions for PNG output files, such as .p100. The issue can be exploited through a CGI program that launches gif2png.

Recommendations For gif2png versions 2.5.3 and earlier, update to a version later than 2.5.3 to resolve the issue. As a temporary workaround, consider restricting the use of gif2png with untrusted input to minimize the risk of exploitation.
