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 score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

  • CCM tag length should be limited to known values (BZ#2144535)
  • 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#2144537)
  • dracut-cmdline[554]: Error in GnuTLS initialization: Error while performing self checks i FIPS mode (BZ#2149640)
