Fortra BoKS Manager contains an out-of-bounds read vulnerability in the custom TLS ClientHello parser used by boks_portmux. A remote unauthenticated attacker can submit a malformed ClientHello and terminate boks_portmux. Although the daemon is normally restarted automatically, repeated requests can sustain the service interruption.
