"Two vulnerabilities were found in the Archive_Tar PHP module, used by
Drupal, which could result in the execution of arbitrary code if a
malicious user is allowed to upload tar archives.

For Debian 9 stretch, these problems have been fixed in version
7.52-2+deb9u13.

We recommend that you upgrade your drupal7 packages.

For the detailed security status of drupal7 please refer to its
