CVE-2006-4256 medium priority: Ubuntu including 1 source packages (horde3), 9 status rows across 9 suites (dapper, edgy, feisty, gutsy, hardy, intrepid, jaunty, karmic, upstream): released 7, ignored 1, needs-triage 1.
index.php in Horde Application Framework before 3.1.2 allows remote attackers to include web pages from other sites, which could be useful for phishing attacks, via a URL in the url parameter, aka "cross-site referencing."
