First published: Tue Mar 14 2023(Updated: )

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.<br>Security Fix(es):<br><li> openssl: X.400 address type confusion in X.509 GeneralName (CVE-2023-0286)</li> <li> openssl: read buffer overflow in X.509 certificate verification (CVE-2022-4203)</li> <li> openssl: timing attack in RSA Decryption implementation (CVE-2022-4304)</li> <li> openssl: double free after calling PEM_read_bio_ex (CVE-2022-4450)</li> <li> openssl: use-after-free following BIO_new_NDEF (CVE-2023-0215)</li> <li> openssl: invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216)</li> <li> openssl: NULL dereference validating DSA public key (CVE-2023-0217)</li> <li> openssl: NULL dereference during PKCS7 data verification (CVE-2023-0401)</li> 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.<br>Bug Fix(es):<br><li> HMAC generation should reject key lengths &lt; 112 bits or provide an indicator in FIPS mode (BZ#2144001)</li> <li> In FIPS mode, openssl should set a minimum length for passwords in PBKDF2 (BZ#2144004)</li> <li> stunnel consumes high amount of memory when pestered with TCP connections without a TLS handshake (BZ#2144009)</li> <li> In FIPS mode, openssl should reject SHAKE as digest for RSA-OAEP or provide an indicator (BZ#2144011)</li> <li> 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#2144013)</li> <li> In FIPS mode, openssl should reject RSA signatures with X9.31 padding, or provide an indicator (BZ#2144016)</li> <li> 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#2144018)</li> <li> In FIPS mode, openssl should reject KDF input and output key lengths &lt; 112 bits or provide an indicator (BZ#2144020)</li> <li> In FIPS mode, openssl should reject RSA keys &lt; 2048 bits when using EVP_PKEY_decapsulate, or provide an indicator (BZ#2145171)</li> <li> OpenSSL FIPS checksum code needs update (BZ#2158413)</li>
