Access Bypass: The Content Translation module for Drupal 6.x enables users to make a translation of an existing item of content (a node). In that process the existing node's content is copied into the new node's submission form. The module contains a flaw that allows a user with the 'translate content' permission to potentially bypass normal viewing access restrictions, for example allowing the user to see the content of unpublished nodes even if they do not have permission to view unpublished nodes.
Validation Bypass: When user profile pictures are enabled, the default user profile validation function will be bypassed, possibly allowing invalid user names or e-mail addresses to be submitted.
Hardening against SQL injection: A parameter passed into the node access API was not properly escaped or validated before being used in SQL queries. While there is no direct risk of SQL injection from Drupal core, it's possible that this could have presented a risk in combination with a contributed module. Additional validation has been added to eliminate this risk.
