There is a path traversal issue in the Apport crash file \"Package\" and \"SourcePackage\" fields. These fields are used to build a path to the package specific hook files in the /usr/share/apport/package-hooks/ directory. An attacker can exploit this path traversal to execute arbitrary Python files from the local system.","published":"2016-12-17T03:59:00.000Z","lastModified":"2026-06-17T00:56:49.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-22"],"affected":["apport project/apport","canonical/ubuntu linux"],"epss":{"score":0.06549,"percentile":0.93773,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.10241,"percentile":0.95531},{"date":"2026-09-22","score":0.06549,"percentile":0.93501}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2016-12-14","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":40937,"kind":"exploit","title":"Apport 2.x (Ubuntu Desktop 12.10 < 16.04) - Local Code Execution","url":"https://www.exploit-db.com/exploits/40937","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/40937.txt","file":"exploits/linux/local/40937.txt","published":"2016-12-14","added":"2016-12-19","updated":"2016-12-19","author":"Donncha OCearbhaill","type":"local","platform":"linux","port":null,"verified":false,"codes":["CVE-2016-9951","CVE-2016-9950","CVE-2016-9949"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://donncha.is/2016/12/compromising-ubuntu-desktop/"}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB and the impact is high, while EPSS rates exploitation at 6.5%.
