Name of the Vulnerable Software and Affected Versions Leptonica versions prior to 1.80.0

Description The issue is related to a heap-based buffer over-read in the pixReadFromTiffStream function, which is connected to the tiffio.c component. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For versions prior to 1.80.0, update to version 1.80.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the pixReadFromTiffStream function until a patch is available.
