Calendar Grey June 21, 2023
Dist Redhat Esm H88
Red Hat's latest advisory on the OpenSSL package highlights crucial updates for addressing moderate security vulnerabilities, urging users to review the changes promptly
An update for openssl is now available for Red Hat Enterprise Linux 9

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

Summary

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es):
* openssl: Possible DoS translating ASN.1 object identifiers(CVE-2023-2650)
* openssl: Denial of service by excessive resource usage in verifying X509 policy constraints (CVE-2023-0464)
* openssl: Invalid certificate policies in leaf certificates are silently ignored (CVE-2023-0465)
* openssl: Certificate policy check not enabled (CVE-2023-0466)
* openssl: Input buffer over-read in AES-XTS implementation on 64 bit ARM (CVE-2023-1255)
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):
* In FIPS mode, openssl KDFs should only allow selected hash algorithms (BZ#2175860)
* In FIPS mode, openssl should reject short KDF input or output keys or provide an indicator (BZ#2175864)
* In FIPS mode, openssl should provide an indicator for AES-GCM to query whether the IV was generated internally or provided externally (BZ#2175868)
* openssl FIPS mode self-test should zeroize `out` in `verify_integrity` in providers/fips/self_test.c (BZ#2175873)
* In FIPS mode, openssl should not support RSA encryption or decryption without padding (outside of RSASVE) or provide an indicator (BZ#2178029)
* In FIPS mode, openssl should reject EVP_PKEY_fromdata() for short DHX keys, or provide an indicator (BZ#2178030)
* In FIPS mode, openssl should not use the legacy ECDSA_do_sign(), RSA_public_encrypt(), RSA_private_decrypt() functions for pairwise consistency tests (BZ#2178034)
* In FIPS mode, openssl should enter error state when DH PCT fails (BZ#2178039)
* In FIPS mode, openssl should always run the PBKDF2 lower bounds checks or provide an indicator when the pkcs5 parameter is set to 1 (BZ#2178137)
* Support requiring EMS in TLS 1.2, default to it when in FIPS mode (BZ#2188046)
* OpenSSL rsa_verify_recover doesn't use the same key checks as rsa_verify in FIPS mode (BZ#2188052)
* RHEL9.0 - sshd dumps core when ibmca engine is configured with default_algorithms = CIPHERS or ALL (openssl) (BZ#2211396)
