CVE-2014-5019: The multisite feature in Drupal 6.x before 6.32 and 7.x before 7.29 allows remote attackers to cause a deni...

Security readout for executives and security teams

This is an older Drupal core denial-of-service issue. A remote attacker could send a specially crafted Host header to affected Drupal multisite installations, interfering with how Drupal selects the right configuration file. The reported impact is service disruption, not data theft or code execution. Exposure is most likely where public Drupal 6.x or 7.x sites use multisite hosting and remained below 6.32 or 7.29. Single-site deployments or patched vendor packages may not be affected, but the provided data does not fully define all deployment conditions. Treat this as a moderate operational availability risk for legacy Drupal multisite estates. It is not presented as data compromise, but public web availability can still affect revenue, reputation, and support load. Mitigation focus: Upgrade Drupal core to 6.32, 7.29, or a vendor-supported fixed package.; Apply Debian or Drupal security guidance where those packages are used.; Prioritize public multisite Drupal deployments for remediation review..
