HCE2-SA-2022-0030 Important HCE 2.0 Security Fix(es): libtiff's tiffcrop utility has a improper input validation flaw that can 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) LibTIFF 4.4.0 has an out-of-bounds read in extractImageSection in tools/tiffcrop.c:6905, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 48d6ece8. (CVE-2022-2953) libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.
