  "title": "Out-of-bounds write in ImageSharp tiled TIFF decoding",
  "summary": "ImageSharp versions before 4.1.1 can write outside a tile buffer while decoding tiled TIFF images using fax compression. An attacker who can supply such an image to an application may cause process termination and memory corruption; the application must decode attacker-controlled tiled, fax-compressed TIFF content.",
  "mitigation": "Upgrade ImageSharp to version 4.1.1 or later. Until upgraded, reject untrusted tiled TIFF files that use fax compression before decoding.",
