GnuPG: interaction between the sks-keyserver code and GnuPG allows for a Certificate Spamming Attack which leads to persistent DoS

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...
