    Allocation of Resources Without Limits or Throttling

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via readNEVariables(). An attacker can exhaust the JVM heap memory by sending a large number of unique Telnet NEW-ENVIRON variable pairs before the terminating IAC SE byte, resulting in an OutOfMemoryError.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade org.jline:jline-remote-telnet to version 4.2.1 or higher.

    Allocation of Resources Without Limits or Throttling

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the TelnetIO.handleNAWS() method, which does not check for upper bounds on requested dimensions. An attacker can cause CPU exhaustion by large NAWS (Negotiate About Window Size) requests with alternating large values over unauthenticated Telnet connections, triggering repeated, resource-intensive rendering cycles on the server.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade org.jline:jline-remote-telnet to version 4.2.1 or higher.
