RHEL 9 : openssl (RHSA-2023:3722)
critical Nessus Plugin ID 177529
Language:
Synopsis
The remote Red Hat host is missing one or more security updates for openssl.Description
The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3722 advisory.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)
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL openssl package based on the guidance in RHSA-2023:3722.See Also
