The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35523)
- A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-35524)
