Package: drupal7 Version: 7.32-1+deb8u3~bpo70+1 Tags: patch,security Severity: grave
Hi! As SA-CORE-2015-003[1] is already public, I extracted the patch (diff between 7.38 and 7.39 plus removed the version bumps). It would be great if you could upload to wheezy-backports too (SA-CORE-2015-002 is missing for this version too, afaik)... Thanks! -- Adi [1] https://www.drupal.org/SA-CORE-2015-003
