"The version of util-linux installed on the remote host is prior to 2.37.4 / 2.40. It is, therefore, affected by a
vulnerability as referenced in the SSA:2024-088-02 advisory.

  - wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to
    be sent to other users' terminals through argv. (Specifically, escape sequences received from stdin are
    blocked, but escape sequences received from argv are not blocked.) There may be plausible scenarios where
    this leads to account takeover. (CVE-2024-28085)

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