"The remote host is affected by the vulnerability described in GLSA-202506-13 (Konsole: Code execution)

    Konsole supports loading URLs from the scheme handlers such as telnet://URL. This can be executed
    regardless of whether the telnet binary is available. It would fallback to bash in that case and execute
    arbitrary code.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
