CVE-2022-2869

Description

libtiff's tiffcrop tool has a uint32_t underflow which leads to out of bounds read and write in the extractContigSamples8bits routine. An attacker who supplies a crafted file to tiffcrop could trigger this flaw, most likely by tricking a user into opening the crafted file with tiffcrop. Triggering this flaw could cause a crash or potentially further exploitation. #### Bugs * <https://gitlab.com/libtiff/libtiff/-/issues/352> #### Notes Author| Note ---|--- [rodrigo-zaiden](<https://launchpad.net/~rodrigo-zaiden>) | fix is the same commit as in CVE-2022-2867, CVE-2022-2868
