A remote attacker could exploit this vulnerability by providing a maliciously crafted Tagged Image File Format (TIFF) file. This could cause the image decoding process to attempt to allocate up to 4 gigabytes (GiB) of memory. The excessive resource consumption or an out-of-memory error would lead to a Denial of Service (DoS) condition." ],
