Details

It was discovered that LibTIFF could be made to read out of bounds when
processing certain malformed image files with the tiffcrop utility. If a
user were tricked into opening a specially crafted image file, an attacker
could possibly use this issue to cause tiffcrop to crash, resulting in a
denial of service.
