This may result in leaving temporary files behind on cleanup. Given automated and repeated execution of dpkg-deb commands on\nadversarial .deb packages or with well compressible files, placed\ninside a directory with permissions not allowing removal by a non-root\nuser, this can end up in a DoS scenario due to causing disk quota\nexhaustion or disk full conditions.","published":"2025-07-01T17:15:30.000Z","lastModified":"2026-07-08T09:16:29.000Z","status":"Modified","sourceIdentifier":"security@debian.org","cvss":{"version":"3.1","score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},"cwe":["CWE-400","CWE-732"],"affected":["debian/dpkg"],"epss":{"score":0.00478,"percentile":0.40976,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.48%).
