{"id":"DEBIAN-CVE-2026-42482","details":"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.","modified":"2026-09-14T17:03:11.984257391Z","published":"2026-05-01T14:16:22.577Z","upstream":["CVE-2026-42482"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42482"}],"affected":[{"package":{"name":"hashcat","ecosystem":"Debian:12","purl":"pkg:deb/debian/hashcat?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.2.6+ds1-1","6.2.6+ds2-1","7.1.2+ds1-1","7.1.2+ds1-2","7.1.2+ds1-3","7.1.2+ds1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42482.json"}},{"package":{"name":"hashcat","ecosystem":"Debian:13","purl":"pkg:deb/debian/hashcat?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.2.6+ds2-1","7.1.2+ds1-1","7.1.2+ds1-2","7.1.2+ds1-3","7.1.2+ds1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42482.json"}},{"package":{"name":"hashcat","ecosystem":"Debian:14","purl":"pkg:deb/debian/hashcat?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.2.6+ds2-1","7.1.2+ds1-1","7.1.2+ds1-2","7.1.2+ds1-3","7.1.2+ds1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42482.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
