Multiple vulnerabilities has been found and corrected in gnutls:
  gnutls-cli in GnuTLS before 2.6.6 does not verify the activation
  and expiration times of X.509 certificates, which allows remote
  attackers to successfully present a certificate that is (1) not yet
  valid or (2) no longer valid, related to lack of time checks in the
  _gnutls_x509_verify_certificate function in lib/x509/verify.c in
  libgnutls_x509, as used by (a) Exim, (b) OpenLDAP, and (c) libsoup
  (CVE-2009-1417).
  A vulnerability have been discovered and corrected in GnuTLS
  before 2.8.2, which could allow man-in-the-middle attackers to spoof
  arbitrary SSL servers via a crafted certificate issued by a legitimate
  Certification Authority (CVE-2009-2730).
  Packages for 2008.0 are being provided due to extended support for
  Corporate products.
This update fixes this vulnerability.
