Description:

   This update for rubygem-puma fixes the following issues:

   - Add patches for disabling TLSv1.0 and TLSv1.1 (jsc#SLE-6965):
   - Add CVE-2020-11077.patch (bsc#1172175, CVE-2020-11077)
   - Add CVE-2020-11076.patch (bsc#1172176, CVE-2020-11076)
   - Add CVE-2020-5247.patch (bsc#1165402) "Fixes a problem where we were not
     splitting newlines in headers according to Rack spec" The patch is
     reduced compared to the upstream version, which was patching also the
     parts that are not implemented in our old Puma version. This applies to
     unit test as well.
   - Add CVE-2019-16770.patch (bsc#1158675, SOC-10999, CVE-2019-16770) This
     patch fixes a DoS vulnerability a malicious client could use to block a
     large amount of threads.
