Ubuntu 16.04 ESM : LibTIFF vulnerabilities (USN-5604-1)

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5604-1 advisory. - 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) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
