- SA-CORE-2021-004

Project:       Drupal core

Date:          2021-July-21

Security risk: Critical 15∕25
               AC:Complex/A:User/CI:All/II:All/E:Theoretical/TD:Uncommon

Vulnerability: Drupal core - Critical - Third-party libraries

CVE IDs:       CVE-2021-32610


Description:

The 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 .


Solution:

Install the latest version:

  o If you are using Drupal 9.2, update to Drupal 9.2.2 .
  o If you are using Drupal 9.1, update to Drupal 9.1.11 .
  o If you are using Drupal 8.9, update to Drupal 8.9.17 .
  o If you are using Drupal 7, update to Drupal 7.82 .

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to
9.1.x are  end-of-life and do not receive security coverage.
