Description: A information disclosure issue exists due to the use of weak hash algorithms by TLS components. This could allow an attacker to obtain information to further compromise a user's encrypted transmission channel. To exploit this, an attacker would have to conduct a man-in-the-middle attack. The issue is related to the implementation of the TLS protocol and its use of weak hash algorithms, which could allow a remote attacker to gain unauthorized access to protected information.
