Multiple security vulnerabilities have been identified in OpenSSL, affecting Red Hat Enterprise Linux 10.0 Extended Update Support and related variants. These include information disclosure, data tampering, denial of service, acceptance of forged messages, unbounded memory growth, and use-after-free issues. The vulnerabilities impact various cryptographic operations such as OCB encryption/decryption, RSA public key handling, CMS EnvelopedData processing, QUIC PATH_CHALLENGE handling, and PKCS7 verification. Red Hat has issued an important security advisory with updates to address these issues.
