Description:
libtiff's tiffcrop utility has a uint32_t underflow that can lead to out

tiffcrop (likely via tricking a user to run tiffcrop on it with certain
parameters) could cause a crash or in some cases, further exploitation.
(CVE-2022-2867)

lead to out of bounds read and ultimately cause a crash if an attacker is
able to supply a crafted file to tiffcrop. (CVE-2022-2868)

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. (CVE-2022-2869)
