[slackware-security]  gnutls (SSA:2019-086-01)

New gnutls packages are available for Slackware 14.2 and -current to
fix security issues.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/gnutls-3.6.7-i586-1_slack14.2.txz:  Upgraded.
  Fixes security issues:
  libgnutls, gnutls tools: Every gnutls_free() will automatically set
  the free'd pointer to NULL. This prevents possible use-after-free and
  double free issues. Use-after-free will be turned into NULL dereference.
  The counter-measure does not extend to applications using gnutls_free().
  libgnutls: Fixed a memory corruption (double free) vulnerability in the
  certificate verification API. Reported by Tavis Ormandy; addressed with
  the change above. [GNUTLS-SA-2019-03-27, #694]
  libgnutls: Fixed an invalid pointer access via malformed TLS1.3 async
  messages; Found using tlsfuzzer. [GNUTLS-SA-2019-03-27, #704]
  libgnutls: enforce key usage limitations on certificates more actively.
  Previously we would enforce it for TLS1.2 protocol, now we enforce it
  even when TLS1.3 is negotiated, or on client certificates as well. When
  an inappropriate for TLS1.3 certificate is seen on the credentials
  structure GnuTLS will disable TLS1.3 support for that session (#690).
  libgnutls: enforce the equality of the two signature parameters fields
  in a certificate. We were already enforcing the signature algorithm,
  but there was a bug in parameter checking code.
  (* Security fix *)
