  "title": "Out-of-bounds write in ImageSharp TIFF decoding",
  "summary": "ImageSharp versions 3.0.0 through 4.1.0 can write beyond an internal buffer while decoding certain CCITT-compressed strip TIFF images. An attacker who can supply such an image to an application that loads untrusted TIFF files may crash the process or corrupt heap memory.",
