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: AES-SIV cipher implementation contains a bug that causes it to ignore empty associated data entries (CVE-2023-2975)
* 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)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.4 Release Notes linked from the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
