(RHSA-2023:1199) 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 PEM_read_bio_ex (CVE-2022-4450)

• openssl: use-after-free following BIO_new_NDEF (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: NULL dereference during PKCS7 data verification (CVE-2023-0401)

Bug Fix(es):

• HMAC generation should reject key lengths < 112 bits or provide an indicator in FIPS mode (BZ#2144001)

• In FIPS mode, openssl should set a minimum length for passwords in PBKDF2 (BZ#2144004)

• stunnel consumes high amount of memory when pestered with TCP connections without a TLS handshake (BZ#2144009)

• In FIPS mode, openssl should reject SHAKE as digest for RSA-OAEP or provide an indicator (BZ#2144011)

• In FIPS mode, openssl should reject RSA signatures with X9.31 padding, or provide an indicator (BZ#2144016)

• 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)

• In FIPS mode, openssl should reject KDF input and output key lengths < 112 bits or provide an indicator (BZ#2144020)

• In FIPS mode, openssl should reject RSA keys < 2048 bits when using EVP_PKEY_decapsulate, or provide an indicator (BZ#2145171)
