How to fix?

Upgrade Debian:9 fuse-exfat to version 1.2.1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fuse-exfat package and not the fuse-exfat package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Heap-based buffer overflow in the verify_vbr_checksum function in exfatfsck in exfat-utils before 1.2.1 allows remote attackers to cause a denial of service (infinite loop) or possibly execute arbitrary code via a crafted filesystem.
