Upgrade Debian:10

NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby2.5
package and not the ruby2.5
package as distributed by Debian
.
See How to fix?
for Debian:10
relevant fixed versions and status.
An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check.
