EulerOS 2.0 SP8 : libtiff (EulerOS-SA-2022-2469)

Description

According to the versions of the libtiff packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Divide By Zero error in tiffcrop in libtiff 4.4.0 allows 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 f3a5e010. (CVE-2022-2056, CVE-2022-2057, CVE-2022-2058) - 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) - A stack overflow was discovered in the _TIFFVGetField function of Tiffsplit v4.4.0. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted TIFF file. (CVE-2022-34526) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
