[slackware-security] gnutls

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pointer no longer valid after realloc.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]
