 Vulnerabilities Multiple flaws

Kurt etc. - no CVE REJECT decisions yet, please.  We might be dealing with a CVE *triplicate*.

There have been a lot of disclosures about swfupload.swf lately with... ummm... mixed levels of detail and varying levels of researcher skill and diligence.  For example, the movieName parameter vector was given CVE-2012-3414 by Kurt in July of 2012, for an April 2012 disclosure - https://nealpoole.com/blog/2012/05/xss-and-csrf-via-swf-applets-swfupload-plupload/  (assignment is in http://www.openwall.com/lists/oss-security/2012/07/17/12 but is listed for the "libjs-swfupload" package).  The CVE-2013-4145 that Kurt just assigned also involves the movieName vector.

Since swfupload.swf is apparently widely used, researchers may be finding the same issue over and over again in different packages, and presenting them as if they are new.  Yet there might be some attack variants buried in there, too.

Because of the amount of attention by researchers who don't check whether an issue has already been disclosed, and/or the number of independent products that use this library, any "new" swfupload.swf issues should be regarded with extreme suspicion while CVE tries to iron out all the existing duplicates.

>CVE-2013-4145 (XSS) is actually CVE-2012-2399.

CVE-2012-2399's only public details are that it's an unspecified vulnerability in Wordpress before 3.3.2, yet http://wordpress.org/news/2012/04/wordpress-3-3-2/ is pretty vague and mentions multiple products (although it does credit Neal Poole for at least one issue).  That said, a statement by a lead developer of Wordpress is important for this clarification ;-)  Andrew, can you confirm for sure that CVE-2012-2399 is *also* the same as CVE-2012-3414 for Neal Poole's movieName vector?

- Steve
