Details

SixLabors ImageSharp Has Infinite Loop in GIF Decoder When Skipping Malformed Comment Extension Blocks ### Impact A specially crafted GIF file containing a malformed comment extension block (with a missing block terminator) can cause the ImageSharp GIF decoder to enter an infinite loop while attempting to skip the block. This leads to a denial of service. Applications processing untrusted GIF input should upgrade to a patched version. ### Patches The problem has been patched. All users are advised to upgrade to v3.1.11 or v2.1.11. ### Workarounds None.
