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: 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 PEMreadbio_ex (CVE-2022-4450)
• openssl: use-after-free following BIOnewNDEF (CVE-2023-0215)
• openssl: invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216)
• openssl: NULL dereference validating DSA public key (CVE-2023-0217)
• openssl: X.400 address type confusion in X.509 GeneralName (CVE-2023-0286)
• openssl: NULL dereference during PKCS7 data verification (CVE-2023-0401)
