This update also fixes CVEs PDO12 and PDO15, which are both tiffcrop denial-of-service issues. The tiffcrop utility is included in the libtiff package and is used to resize and convert TIFF images. It is activated by default on most Linux distributions. In addition to the aforementioned CVEs, this advisory also includes fixes for several other bugs. The Common Vulnerability Scoring System (CVSS) rating for these fixed vulnerabilities is 8.3. With this update, tiffcrop no longer allows users to provide an unchecked return value to NULL pointer dereference, which prevents a denial-of-service attack. Additionally, this update fixes a memory leak vulnerability that could be exploited by attackers to cause a denial-of-service via a crafted TIFF file.
