CVE-2026-42482 (GCVE-0-2026-42482)
Vulnerability from cvelistv5 – Published: 2026-05-01 00:00 – Updated: 2026-05-01 18:36
VLAI?
Summary
A stack-based buffer overflow in mangle_to_hex_lower() and mangle_to_hex_upper() in src/rp_cpu.c in hashcat v7.1.2 allows an attacker to cause a denial of service or possibly execute arbitrary code via a crafted rule file, or via the -j or -k rule options used with password candidates of 128 or more characters. The vulnerability is caused by a bounds check that fails to account for the 2x expansion that occurs when password bytes are converted to hexadecimal.

CVE-2026-42483 (GCVE-0-2026-42483)
Vulnerability from cvelistv5 – Published: 2026-05-01 00:00 – Updated: 2026-05-01 17:36

Summary
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.

CVE-2026-42484 (GCVE-0-2026-42484)
Vulnerability from cvelistv5 – Published: 2026-05-01 00:00 – Updated: 2026-05-01 18:35
VLAI?
Summary
A heap-based buffer overflow in hex_to_binary in the PKZIP hash parser in hashcat v7.1.2 allows an attacker to cause a denial of service or possibly execute arbitrary code via a crafted PKZIP hash file. The issue affects modules 17200, 17210, 17220, 17225, and 17230. When data_type_enum<=1, attacker-controlled hex data from a user-supplied hash string is decoded into a fixed-size buffer without proper input-length validation.
