Package : drupal7
Version : 7.52-2+deb9u12
CVE ID : CVE-2020-13666 CVE-2020-13671

Two vulnerabilities were discovered in Drupal, a fully-featured content
management framework.

CVE-2020-13666

The Drupal AJAX API did not disable JSONP by default, which could
lead to cross-site scripting.

For setups that relied on Drupal's AJAX API for JSONP requests,
either JSONP will need to be reenabled, or the jQuery AJAX API will
have to be used instead.

See the upstream advisory for more details:
https://www.drupal.org/sa-core-2020-007

CVE-2020-13671

Drupal failed to sanitize filenames on uploaded files, which could
lead to those files being served as the wrong MIME type, or being
executed depending on the server configuration.

It is also recommended to check previously uploaded files for
malicious extensions. For more details see the upstream advisory:
https://www.drupal.org/sa-core-2020-012

For Debian 9 stretch, these problems have been fixed in version
7.52-2+deb9u12.

We recommend that you upgrade your drupal7 packages.
