What to do

AI-suggested

  1. Upgrade RenderDoc to version 1.27 or later as soon as the patch is available to eliminate the vulnerability.
  2. Until patching is possible, restrict write permissions to the /tmp directory and specifically to /tmp/RenderDoc to trusted users only, preventing unauthorized symlink creation.
  3. Implement monitoring and alerting for suspicious symlink creation or modification activities within /tmp, using file integrity monitoring tools.
  4. Enforce the use of secure temporary directories with proper ownership and permissions, avoiding reliance on world-writable directories for sensitive operations.
  5. Educate developers and system administrators about the risks of symlink attacks and secure handling of temporary files.
  6. Consider running RenderDoc with the least privileges necessary and within isolated environments or containers to limit the impact of potential exploitation.
  7. Regularly audit local user permissions and access controls to minimize the number of users who can perform local operations that might exploit this vulnerability.

Description

RenderDoc before 1.27 allows local privilege escalation via a symlink attack. It relies on the /tmp/RenderDoc directory regardless of ownership.
