An update that solves four vulnerabilities, contains one feature and has eight
security fixes can now be installed.

## Description:

This update for gnutls fixes the following issues:

Security issues fixed:

  * CVE-2023-0361: Fixed a Bleichenbacher oracle in the TLS RSA key exchange
    (bsc#1208143).
  * CVE-2023-5981: Fixed timing side-channel inside RSA-PSK key exchange
    (bsc#1217277).
  * CVE-2024-0567: Fixed an incorrect rejection of certificate chains with
    distributed trust (bsc#1218862).
  * CVE-2024-0553: Fixed a timing attack against the RSA-PSK key exchange, which
    could lead to the leakage of sensitive data (bsc#1218865).

FIPS 140-3 certification related bugs fixed:

  * FIPS: Set error state when jent init failed in FIPS mode (bsc#1202146)
  * FIPS: Make XTS key check failure not fatal (bsc#1203779)
  * FIPS: Added GnuTLS DH/ECDH pairwise consistency check for public key
    regeneration [bsc#1207183]
  * FIPS: Change all the 140-2 references to FIPS 140-3 in order to account for
    the new FIPS certification [bsc#1207346]
  * FIPS: Make the jitterentropy calls thread-safe (bsc#1208146).
  * FIPS: GnuTLS DH/ECDH PCT public key regeneration (bsc#1207183).
  * FIPS: Fix pct_test() return code in case of error (bsc#1207183)
  * FIPS: Establish PBKDF2 additional requirements [bsc#1209001]

  * Set the minimum output key length to 112 bits (FIPS 140-3 IG D.N)

  * Set the minimum salt length to 128 bits (SP 800-132 sec. 5.1)
  * Set the minimum iterations count to 1000 (SP 800-132 sec 5.2)
  * Set the minimum passlen of 20 characters (SP SP800-132 sec 5)
  * Add regression tests for the new PBKDF2 requirements.

Other issues fixed:

  * Fix AVX CPU feature detection for OSXSAVE (bsc#1203299) This fixes a SIGILL
    termination at the verzoupper instruction when trying to run GnuTLS on a
    Linux kernel with the noxsave command line parameter set. Relevant mostly
    for virtual systems.
  * Increase the limit of TLS PSK usernames from 128 to 65535 characters.
