Name of the Vulnerable Software and Affected Versions ImageWorsener version 1.3.1

Description The issue allows remote attackers to cause a denial of service, resulting in an infinite loop, by providing a crafted image. This is due to a problem in the lzw add to dict function in imagew-gif.c in libimageworsener.a.

Recommendations For ImageWorsener version 1.3.1, consider avoiding the use of the lzw add to dict function until a patch is available.
