Drupal Core contains a SQL injection vulnerability that could allow for privilege escalation and remote code execution via specially crafted requests sent with the database abstraction API.
A flaw was found in the ArchiveTar package. ArchiveTar could allow a remote attacker to traverse directories on the system caused by inadequate checking of symbolic links. An attacker could send a specially-crafted URL request to the Tar.php script containing "dot dot" sequences (/../) to modify arbitrary files on the system.
