Hi,

has there already been a CVE assigned for the recent "lucky 13" timing
flaw that affects various SSL / TLS implementations (including GnuTLS)?

  http://www.isg.rhul.ac.uk/tls/
  http://www.gnutls.org/security.html#GNUTLS-SA-2013-1

I think this could qualify for CVE for each open source implementation
that's prone.

openssl has released updated packages with a CVE assigned, unclear
whether it covers just openssl or also the others.

http://www.openssl.org/news/secadv_20130205.txt

cc'ing cve-assign to see if they can provide some guidance here.  I also
noticed that OpenSSL has a CVE for this (I'm assuming that the
CVE-2012-2686 issue is _not_ the same thing, but that CVE-2013-0169 is
this issue).

Since it's a weakness in TLS/DTLS itself, from my understanding, and not
necessarily in a particular implementation, I'm not sure if this
qualifies as one CVE for the weakness, or if it needs one per
implementation.

MITRE, can someone provide some guidance on this?
