CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to heap-based buffer overflow in the tiffload operation when decoding a TIFF image containing a crafted JPEG or JPEG2000-encoded tile. A remote attacker can supply a specially crafted TIFF image to execute arbitrary code.
