Drupal core - Critical - Drupal core - Critical - Third-party libraries - SA-CORE-2021-004
Project: Drupal core
Date: 2021-July-21
Security risk: Critical 15â\x{136}\x{149}25
AC:Complex/A:User/CI:All/II:All/E:Theoretical/TD:Uncommon
Vulnerability: Drupal core - Critical - Third-party libraries
CVE IDs: CVE-2021-32610Description:
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.
