A flaw was found in libtiff's tiffcrop tool that has a uint32_t underflow, which leads to an out-of-bounds read and write in the extractContigSamples8bits routine. This flaw allows an attacker who supplies a crafted file to tiffcrop to trick a user into opening the crafted file with tiffcrop, causing a crash or potential further exploitations.
