CVE intelligence and bounded remediation
CVE-2016-4989 — Setroubleshoot Project Setroubleshoot security vulnerability
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.

Command, code, expression, and template injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
- Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
- Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.
Remediate safely
- Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
- Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
- Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
