Описание
setroubleshoot allows local users to bypass an intended container protection mechanism and execute arbitrary commands by (1) triggering an SELinux denial with a crafted file name, which is handled by the _set_tpath function in audit_data.py or via a crafted (2) local_id or (3) analysis_id field in a crafted XML document to the run_fix function in SetroubleshootFixit.py, related to the subprocess.check_output and commands.getstatusoutput functions, a different vulnerability than CVE-2016-4445.
Shell command injection flaws were found in the way the setroubleshoot executed external commands. A local attacker able to trigger certain SELinux denials could use these flaws to execute arbitrary code with root privileges.
