Description Dhananjay Arunesh 2023-08-28 08:46:51 UTC 
Multiple potential integer overflow in tiffcp.c in libtiff <= 4.5.1 can allow remote attackers to cause a denial of service (application crash) or possibly execute an arbitrary code via a crafted tiff image which triggers a heap-based buffer overflow.
