GnuPG version 2.1.12 - 2.2.11 contains a Cross ite Request Forgery (CSRF) vulnerability in dirmngr that can result in Attacker controlled CSRF, Information Disclosure, DoS. This attack appear to be exploitable via Victim must perform a WKD request, e.g. enter an email address in the composer window of Thunderbird/Enigmail. This vulnerability appears to have been fixed in after commit 4a4bb874f63741026bd26264c43bb32b1099f060.

This vulnerability appears to have been fixed in after commit     4a4bb874f63741026bd26264c43bb32b1099f060. (CVE-2018-1000858)

  - Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through     2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS     keyserver network. Retrieving data from this network may cause a persistent denial of service, because of     a Certificate Spamming Attack. (CVE-2019-13050)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
