Description

A information disclosure vulnerability exists when TLS components use weak hash algorithms. An attacker who successfully exploited this vulnerability could obtain information to further compromise a users&amp;#39;s encrypted transmission channel.<br /> To exploit the vulnerability, an attacker would have to conduct a man-in-the-middle attack.<br /> The update addresses the vulnerability by correcting how TLS components use hash algorithms.
