{"id":"CVE-2017-7572","details":"The _checkPolkitPrivilege function in serviceHelper.py in Back In Time (aka backintime) 1.1.18 and earlier uses a deprecated polkit authorization method (unix-process) that is subject to a race condition (time of check, time of use). With this authorization method, the owner of a process requesting a polkit operation is checked by polkitd via /proc/\u003cpid\u003e/status, by which time the requesting process may have been replaced by a different process with the same PID that has different privileges then the original requester.","modified":"2026-05-17T11:54:06.291386779Z","published":"2017-04-06T18:59:00.353Z","related":["openSUSE-SU-2024:10647-1"],"database_specific":{},"references":[{"type":"ADVISORY","url":"https://github.com/bit-team/backintime/commit/7f208dc547f569b689c888103e3b593a48cd1869"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
