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: Incorrect cipher key and IV length processing (CVE-2023-5363)

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):

  • Backport implicit rejection mechanism for RSA PKCS#1 v1.5 to RHEL-9.2.z (RHEL-14578, BZ#2153471)
  • OpenSSL should provide FIPS-compliant RSA-OAEP (RHEL-14616)
  • NIST SP 800-56Arev3 Section 5.6.2.1 - Missing ECDH Public Key Check (RHEL-15992)
  • In FIPS mode, OpenSSL must not perform any cryptographic operations when rsa_keygen_pairwise_test fails (RHEL-17110)
