libtiff security updateSummary:

An update for libtiff is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS.Description:

Security Fix(es):

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.(CVE-2022-2867)

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)Topic:
