RHSA-2023:0946: Important: openssl security and bug fix update
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: X.400 address type confusion in X.509 GeneralName (CVE-2023-0286) openssl: read buffer overflow in X.509 certificate verification (CVE-2022-4203) openssl: timing attack in RSA Decryption implementation (CVE-2022-4304) openssl: double free after calling PEMreadbioex (CVE-2022-4450) openssl: use-after-free following BIOnewNDEF (CVE-2023-0215) openssl: invalid pointer dereference in d2iPKCS7 functions (CVE-2023-0216) openssl: NULL dereference validating DSA public key (CVE-2023-0217) openssl: NULL dereference during PKCS7 data verification (CVE-2023-0401) 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): HMAC generation should reject key lengths < 112 bits or provide an indicator in FIPS mode (BZ#2144000) In FIPS mode, openssl should set a minimum length for passwords in PBKDF2 (BZ#2144003) stunnel consumes high amount of memory when pestered with TCP connections without a TLS handshake (BZ#2144008) In FIPS mode, openssl should reject SHAKE as digest for RSA-OAEP or provide an indicator (BZ#2144010) In FIPS mode, openssl should reject RSASSA-PSS salt lengths larger than the output size of the hash function used, or provide an indicator (BZ#2144012) In FIPS mode, openssl should reject RSA signatures with X9.31 padding, or provide an indicator (BZ#2144015) In FIPS mode, openssl should reject SHA-224, SHA-384, SHA-512-224, and SHA-512-256 as hashes for hash-based DRBGs, or provide an indicator after 2023-05-16 (BZ#2144017) In FIPS mode, openssl should reject KDF input and output key lengths < 112 bits or provide an indicator (BZ#2144019) In FIPS mode, openssl should reject RSA keys < 2048 bits when using EVPPKEYdecapsulate, or provide an indicator (BZ#2145170) RHEL9.1 Nightly[0912] - error:03000093:digital envelope routines::command not supported when git clone is run with configured ibmca engine backed by libica.so.4 (OpenSSL 3.0) (BZ#2149010) OpenSSL FIPS checksum code needs update (BZ#2158412)
