Original description
The description as published by the source.
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.
