{"id":"CVE-2026-42484","details":"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\u003c=1, attacker-controlled hex data from a user-supplied hash string is decoded into a fixed-size buffer without proper input-length validation.","modified":"2026-07-08T08:17:38.579984174Z","published":"2026-05-01T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42484.json"},"references":[{"type":"WEB","url":"https://gist.github.com/sgInnora/107f2eb20367e47d58c911e38d56a91f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42484.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42484"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hashcat/hashcat","events":[{"introduced":"c75f446c44cd3f0742035a1394416c39bee5ea8f"},{"last_affected":"c75f446c44cd3f0742035a1394416c39bee5ea8f"}],"database_specific":{"cpe":"cpe:2.3:a:hashcat:hashcat:7.1.2:*:*:*:*:*:*:*","extracted_events":[{"introduced":"7.1.2"},{"last_affected":"7.1.2"}],"source":"CPE_STRING"}}],"versions":["7.1.2","v7.1.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42484.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
