  "title": "tiff: A flaw was found in libtiff",
  "description": "A flaw was found in libtiff. A heap-buffer overflow vulnerability exists in the \u0060tiff2pdf\u0060 utility due to an integer truncation error when processing crafted BigTIFF files. An attacker can provide a specially crafted BigTIFF file, causing a 64-bit \u0060StripByteCounts\u0060 value to be truncated to a 32-bit integer. This leads to an undersized memory allocation and a subsequent out-of-bounds memory copy, resulting in a crash and severe memory corruption.",
