Thank you!  The summary line should include the CVE, like this:

  gnu: libgcrypt: Update to 1.6.5 [fixes CVE-2015-7511].

Alas, this will require at least 7000 rebuilds.  After the current
'security-updates' branch is merged, this should go on the next
'security-updates' branch, together with more fixes for graphite2 and
libsndfile.
