Description
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.
Affected configurations
• gnupg gnupg (<= 2.2.16)
• sks keyserver project sks keyserver (<= 1.2.0)
• fedoraproject fedora 29
• fedoraproject fedora 30
• opensuse leap 15.0
• opensuse leap 15.1
• f5 traffix signaling delivery controller (>= 5.0.0 <= 5.1.0)
