Vulnerability:
Third-party libraries

>=7.0 <7.78 || >= 8.0.0 <8.9.13 || >= 9.0.0 <9.0.11 || >=9.1.0 <9.1.3
Description:
The Drupal project uses the pear Archive_Tar library, which has released a security update that impacts Drupal. For more information please see:
Exploits may be possible if Drupal is configured to allow .tar, .tar.gz, .bz2, or .tlz file uploads and processes them.
Solution:
Install the latest version:
- If you are using Drupal 9.1, update to Drupal 9.1.3.
- If you are using Drupal 9.0, update to Drupal 9.0.11.
- If you are using Drupal 8.9, update to Drupal 8.9.13.
- If you are using Drupal 7, update to Drupal 7.78.
Versions of Drupal 8 prior to 8.9.x are end-of-life and do not receive security coverage.
Disable uploads of .tar, .tar.gz, .bz2, or .tlz files to mitigate the vulnerability.
