CVE-2012-0390 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0390):
  The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain
  error-handling code only if there is a specific relationship between a
  padding length and the ciphertext size, which makes it easier for remote
  attackers to recover partial plaintext via a timing side-channel attack, a
  related issue to CVE-2011-4108.

GnuTLS 2.x does not support DTLS; this issue was fixed in 3.0.11. Our only affected ebuild was =net-libs/gnutls-3.0.10 which was in p.mask while it was in the tree.
