Summary
Moderate: gnupg2 security, bug fix, and enhancement update

The following packages have been upgraded to a later upstream version: gnupg2 (2.2.20). (BZ#1663944)

Security Fix(es):

  • GnuPG: interaction between the sks-keyserver code and GnuPG allows for a Certificate Spamming Attack which leads to persistent DoS (CVE-2019-13050)
