"The version of 7-Zip installed on the remote host is prior to 24.08. It is, therefore, affected by a denial of
service vulnerability as referenced in the ZDI-24-1606 advisory.

  - This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of
    7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary
    depending on the implementation. The specific flaw exists within the processing of streams. The issue results
    from a logic error that can lead to an infinite loop. An attacker can leverage this vulnerability to create a
    denial-of-service condition on the system. (CVE-2024-11612)

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