  • GHSA-p8q8-jfcv-g2h2Directory Traversal in Archive_Tar2021-08-09ghsa · osvUS

    In Archive_Tar before 1.4.14, symlinks can refer to targets outside of the extracted archive, a different vulnerability than CVE-2020-36193.

  • DRUPAL-CORE-2021-0042021-07-21vendor · osvUS

    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](/steward).
