Description:
6
 
 The _checkPolkitPrivilege function in serviceHelper.py in Back In Time (aka
7
 
 backintime) 1.1.18 and earlier uses a deprecated polkit authorization
8
 
 method (unix-process) that is subject to a race condition (time of check,
9
 
 time of use). With this authorization method, the owner of a process
10
 
 requesting a polkit operation is checked by polkitd via /proc/<pid>/status,
11
 
 by which time the requesting process may have been replaced by a different
12
 
 process with the same PID that has different privileges then the original
13
 
 requester.
