Executive Summary

This vulnerability allows a client using TLS 1.2 connections to select any digest algorithm, including weaker ones that are supported, instead of being restricted to the stronger digests specified in the CertificateRequest. This means the client can downgrade the digest algorithm to a less secure option during the TLS handshake.

Impact Analysis

The impact of this vulnerability is that an attacker could potentially exploit the use of weaker digest algorithms during TLS 1.2 connections, which may reduce the overall security of the encrypted communication. This could lead to increased risk of cryptographic attacks such as forgery or interception of data, compromising confidentiality and integrity.
