Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the exec request handling process. An attacker can cause the server process to crash and terminate all active connections by sending a specially crafted five-byte message with a manipulated length field, resulting in an out-of-range slice and unhandled panic. This is only exploitable if the SSH Tunnel Gateway is enabled and no authorized-keys file is set, allowing unauthenticated access.
