Drupal core-Important security update

Vulnerability: Drupal core - Critical - Third-party librariesThe Drupal project uses the pear Archive_Tar library, which has released a security update that impacts Drupal.

The vulnerability is mitigated by the fact that Drupal core's use of the Archive_Tar library is not vulnerable, as it does not permit symlinks.

Exploitation may be possible if contrib or custom code uses the library to extract tar archives (for example .tar, .tar.gz, .bz2, or .tlz) which come from a potentially untrusted source.

This advisory is not covered by Drupal Steward( is a web application firewall that bridges the gap between the time when a security release is announced and when your site is fully updated with the new security patch).
