This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
fontconfig before 2.12.1 does not validate offsets, which allows local users to trigger arbitrary free calls and consequently conduct double free attacks and execute arbitrary code via a crafted cache file.

Description
It was found that cache files were insufficiently validated in fontconfig. A local attacker could create a specially crafted cache file to trigger arbitrary free() calls, which in turn could lead to arbitrary code execution.
