Description Jan Lieskovsky 2011-11-03 14:57:10 UTC 
A local file inclusion flaw was found in the way XML import plug-in of phpMyAdmin, a tool written in PHP intended to handle the administration of MySQL over the World Wide Web, performed import of malformed XML files. A remote attacker could provide a specially-crafted XML file, which once imported into the phpMyAdmin service instance would lead to arbitrary local file (accessible with the privileges of the phpMyAdmin user) read / retrieval.

Comment 3 Jan Lieskovsky 2011-11-03 15:15:23 UTC 
Regarding upstream patches (not sure phpMyAdmin upstream provided a changeset for this issue already, since it was reported two days ago). Cc-ed them on the CVE request for further patch information.
