[slackware-security]  gnutls (SSA:2021-145-01)

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-3.6.16-i586-1_slack14.2.txz:  Upgraded.
  Fixed potential miscalculation of ECDSA/EdDSA code backported from Nettle.
  In GnuTLS, as long as it is built and linked against the fixed version of
  Nettle, this only affects GOST curves.  [CVE-2021-20305]
  Fixed potential use-after-free in sending "key_share" and "pre_shared_key"
  extensions. When sending those extensions, the client may dereference a
  pointer no longer valid after realloc. This happens only when the client
  sends a large Client Hello message, e.g., when HRR is sent in a resumed
  session previously negotiated large FFDHE parameters, because the initial
  allocation of the buffer is large enough without having to call realloc
  (#1151).  [GNUTLS-SA-2021-03-10, CVSS: low]
