Package        : drupal7
Version        : 7.52-2+deb9u16
CVE ID         : CVE-2021-32610

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.

For Debian 9 stretch, this problem has been fixed in version
7.52-2+deb9u16.

We recommend that you upgrade your drupal7 packages.

For the detailed security status of drupal7 please refer to
its security tracker page at:
