Affected o SUSE Linux Enterprise Micro 5.3
Products: o SUSE Linux Enterprise Micro for Rancher 5.3
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:
o CVE-2023-0361: Fixed a Bleichenbacher oracle in the TLS RSA key exchange
(bsc#1208143).
o CVE-2023-5981: Fixed timing side-channel inside RSA-PSK key exchange (bsc#
1217277).
o CVE-2024-0567: Fixed an incorrect rejection of certificate chains with
distributed trust (bsc#1218862).
o 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:
o FIPS: Set error state when jent init failed in FIPS mode (bsc#1202146)
o FIPS: Make XTS key check failure not fatal (bsc#1203779)
o FIPS: Added GnuTLS DH/ECDH pairwise consistency check for public key
regeneration [bsc#1207183]
o FIPS: Change all the 140-2 references to FIPS 140-3 in order to account for
the new FIPS certification [bsc#1207346]
o FIPS: Make the jitterentropy calls thread-safe (bsc#1208146).
o FIPS: GnuTLS DH/ECDH PCT public key regeneration (bsc#1207183).
o FIPS: Fix pct_test() return code in case of error (bsc#1207183)
o FIPS: Establish PBKDF2 additional requirements [bsc#1209001]
o Set the minimum output key length to 112 bits (FIPS 140-3 IG D.N)
o Set the minimum salt length to 128 bits (SP 800-132 sec. 5.1)
o Set the minimum iterations count to 1000 (SP 800-132 sec 5.2)
o Set the minimum passlen of 20 characters (SP SP800-132 sec 5)
o Add regression tests for the new PBKDF2 requirements.
Other issues fixed:
o 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.
o Increase the limit of TLS PSK usernames from 128 to 65535 characters. [bsc#
1208237, jsc#PED-1562]
