3. Description:

The gnutls packages provide the GNU Transport Layer Security (GnuTLS)
library, which implements cryptographic algorithms and protocols such as
SSL, TLS, and DTLS.

Security Fix(es):

* gnutls: timing side-channel in the TLS RSA key exchange code
(CVE-2023-0361)

For more details about the security issue(s), including the impact, a CVSS

page(s) listed in the References section.

Bug Fix(es):

* CCM tag length should be limited to known values (BZ#2144536)

* In FIPS mode, gnutls should reject RSASSA-PSS salt lengths larger than
the output size of the hash function used, or provide an indicator
(BZ#2144538)

* dracut-cmdline[554]: Error in GnuTLS initialization: Error while
performing self checks i FIPS mode (BZ#2149641)
