The version of stunnel installed on the remote host is 4.46 or later but prior to 5.34. It is, therefore, affected by a security bypass vulnerability related to the validation of level 4 peer certificates. An unauthenticated, remote attacker can exploit this to have an impact on confidentiality, integrity, and/or availability. No other details are available. I am of the mind that perhaps an entry in Stunnel.conf until we can deploy an upgrade? Thanks in advance for any feedback! | Upgrade to stunnel version 5.34 or later. |
