CVE-2023-44821

DISPUTED Gifsicle through 1.94, if deployed in a way that allows
untrusted input to affect Gif_Realloc calls, might allow a denial of
service (memory consumption). NOTE: this has been disputed by multiple
parties because the Gifsicle code is not commonly used for unattended
operation in which new input arrives for a long-running process, does not
ship with functionality to link it into another application as a library,
and does not have realistic use cases in which an adversary controls the
entire command line.
