RedHat: RHSA-2023-1141:01 Moderate: gnutls
Summary
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)
