Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002

Project:       Drupal core
Date:          2018-March-28
Security risk: Highly critical
           21/25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:Default
Vulnerability: Remote Code Execution
Description:   CVE: CVE-2018-7600

A remote code execution vulnerability exists within multiple subsystems
of Drupal 7.x and 8.x. This potentially allows attackers to exploit
multiple attack vectors on a Drupal site, which could result in the site
being completely compromised.

The security team has written an FAQ about this issue.

Solution:

Upgrade to the most recent version of Drupal 7 or 8 core.

  * If you are running 7.x, upgrade to Drupal 7.58. (If you are unable
    to update immediately, you can attempt to apply this patch to fix
    the vulnerability until such time as you are able to completely
    update.)
  * If you are running 8.5.x, upgrade to Drupal 8.5.1. (If you are
    unable to update immediately, you can attempt to apply this patch
    to fix the vulnerability until such time as you are able to
    completely update.)

Drupal 8.3.x and 8.4.x are no longer supported and we don't normally
provide security releases for unsupported minor releases. However,
given the potential severity of this issue, we are providing 8.3.x and
8.4.x releases that includes the fix for sites which have not yet had a
chance to update to 8.5.0.

Your site's update report page will recommend the 8.5.x release even if
you are on 8.3.x or 8.4.x. Please take the time to update to a
supported version after installing this security update.

  * If you are running 8.3.x, upgrade to Drupal 8.3.9 or apply this
patch.
  * If you are running 8.4.x, upgrade to Drupal 8.4.6 or apply this
patch.

This issue also affects Drupal 8.2.x and earlier, which are no longer
supported. If you are running any of these versions of Drupal 8, update
to a more recent release and then follow the instructions above.

This issue also affects Drupal 6. Drupal 6 is End of Life. For more
information on Drupal 6 support please contact a D6LTS vendor.
