As far as I'm aware, there was no CVE assigned when the original header injection/response splitting protection was added. I presume there wasn't one because it was a security feature to protect applications that didn't validate what was being passed to header(), not a fix for a vulnerability.  such as phpMyID: http://seclists.org/bugtraq/2008/Oct/4 (which now I notice never got a CVE id) > Although a vulnerability statement such as "First one still has the > possibility of injecting '\r' before the first '\n'" can be associated > with the concept of an incomplete fix, MITRE does not consider the fix > to be an "incomplete fix for" a different CVE (that references a > better patch).

Perhaps I'm misunderstanding something, but the above is confusing me. To me, this is what each of the ids represent: CVE-2011-1398: describes the protection bypass CVE-2012-4388: describes the failure to fully fix the protection bypass (hence the "incomplete fix for CVE-2011-1398") P.S. I don't even mention the NUL-byte issue as, to the best of my knowledge, never made it into a release. Regards, -- Raphael Geissert - Debian Developer www.debian.org - get.debian.net
