Name of the Vulnerable Software and Affected Versions LibTIFF master branch

Description The issue is related to an out-of-bounds read in the LZWDecode function in libtiff/tif lzw.c:619, allowing attackers to cause a denial-of-service via a crafted tiff file. This can be exploited by a remote attacker to disrupt service.

Recommendations For users that compile libtiff from sources, the fix is available with commit b4e79bfa. As a temporary workaround, consider disabling the LZWDecode function until a patch is available. Restrict access to crafted tiff files to minimize the risk of exploitation.
