Component: Not specified by the source

Attack conditions (NVD, CVSS 3.1): Network (remote) · No privileges required · No user interaction required

Attack conditions (Source advisory, CVSS 3.1): Network (remote) · No privileges required · No user interaction required

What an attacker can do

The source says after a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection. NVD’s CVSS 3.1 assessment (base score 5.9/10) rates confidentiality impact as high; integrity and availability impact as none. Source advisory’s CVSS 3.1 assessment (base score 5.9/10) rates confidentiality impact as high; integrity and availability impact as none.
