Summary
Updated exfat-utils package fixes security vulnerabilities
Details

Fix heap overflow and endless loop in exfatfsck

exfat-utils is a collection of tools to work with the exFAT filesystem. Fuzzing the exfatfsck with american fuzzy lop led to the discovery of a write heap overflow and an endless loop.

Especially at risk are systems that are configured to run filesystem checks automatically on external devices like USB flash drives.

A malformed input can cause a write heap overflow in the function verifyvbrchecksum. It might be possible to use this for code execution.

Another malformed input can cause an endless loop, leading to a possible denial of service.
