"The version of pidgin installed on the remote host is prior to 2.12.0 / 2.14.9. It is, therefore, affected by a
vulnerability as referenced in the SSA:2022-120-01 advisory.

  - An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can
    redirect a client connection to a malicious server. The client will perform TLS certificate verification
    of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take
    over control over the XMPP connection and to obtain user credentials and all communication content. This
    is similar to CVE-2022-24968. (CVE-2022-26491)

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