"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3782 advisory.

  - An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker
    were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file.
    NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.
    (CVE-2021-37600)

  - 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 these issues but has instead relied only on the application's self-reported version
number.");
