CVE 2009-3555 for nginx & openssl



Hello,

Although the security team addressed CVE 2009-3555 for apache, my reckoning is that lenny's nginx is still vulnerable to the SSL renegotiation vulnerability detailed in CVE 2009-3555, and that openssl is as well. If that's the case, is it something the security team should address?

To offer some background, lenny's version of nginx is the "old" version, or 0.6 -- and so the nginx authors did not issue a patch for it. However, the 0.7 patch does apply on 0.6, and appears to work -- at least in 0.6.39. (A few important other things, such as nginx's treatment of Vary: headers, may have changed between lenny's rev of 0.6 and 0.6.39, so I can imagine that's complicated things).

But, for what it's worth, it seems like Debian testing, which has the current stable nginx version (0.7), does have the fix (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=557873). It also appears that Red Hat patched this for nginx 0.6 back in December of 2009 (cf. the changelog at http://fr2.rpmfind.net//linux/RPM/epel/5/i386/nginx-0.6.39-2.el5.i386.html).

If it's helpful, the other locus for the vulnerability is OpenSSL. However, their initial patch was -- by their admission in the Changelog -- not quite right in 0.9.8l, and for the same reason doesn't obviate the nginx patch. We await 0.9.8m. That said, the (albeit imperfect) 0.9.8l fix for CVE 2009-3555 also does not seem to be in lenny. Should it be?

Thank you,

Hunter Blanks
