Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2447 advisory.

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: Excessive time spent checking DH keys and parameters (CVE-2023-3446)

* OpenSSL: Excessive time spent checking DH q parameter value (CVE-2023-3817)

* openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow (CVE-2023-5678)

* openssl: POLY1305 MAC implementation corrupts vector registers on PowerPC (CVE-2023-6129)

* openssl: Excessive time spent checking invalid RSA public keys (CVE-2023-6237)

* openssl: denial of service via null dereference (CVE-2024-0727)
