CVE-2023-5678

A flaw was found in OpenSSL, which caused the generation or checking of long X9.42 DH keys or parameters to be much slower than expected. This issue could lead to a denial of service.

This vulnerability in OpenSSL is categorized as a low severity issue primarily because it requires specific conditions to exploit and doesn't directly result in a full Denial of Service (DoS). While the excessive time spent in DH key generation or verification could potentially cause delays, the impact is mitigated by the fact that it requires untrusted sources supplying large Q parameter values. Additionally, the OpenSSL SSL/TLS implementation remains unaffected, limiting the scope of potential attacks. Moreover, there are inherent limits on key length, which further restrict the potential for exploitation.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
