How to fix?

There is no fixed version for Debian:14 hashcat.

NVD Description

Note: Versions mentioned in the description apply only to the upstream hashcat package and not the hashcat package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

A heap-based buffer overflow in the Kerberos hash parser in hashcat v7.1.2 allows an attacker to cause a denial of service or possibly execute arbitrary code via a crafted Kerberos hash file. The issue affects module_hash_decode in multiple Kerberos-related modules because account_info_len is calculated from untrusted delimiter positions without upper-bound validation before memcpy copies the data into a fixed-size account_info buffer.
