K61903372: OpenSSL vulnerability CVE-2021-23839

Security Advisory Description OpenSSL 1.0.2 supports SSLv2. If a client attempts to negotiate SSLv2 with a server that is configured to support both SSLv2 and more recent SSL and TLS versions then a check is made for a version rollback attack when unpadding an RSA signature. Clients that support...

Amazon Linux 2 : openssl11 (ALAS-2021-1612)

The version of openssl11 installed on the remote host is prior to 1.1.1g-12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1612 advisory.
