 - A denial of service (DoS) vulnerability exists in Subversion's svnserve server process due to that the process may exit
   when a well-formed read-only request produces a particular answer. A remote authenticated attacker can exploit this issue
   to cause a denial of service attack. (CVE-2018-11782)

 - A denial of service (DoS) vulnerability exists in Subversion's svnserve server process due to that the process may exit
   when a client sends certain sequences of protocol commands. A remote unauthenticated attacker can exploit this issue,
   If the server is configured with anonymous access enabled, to cause a remote denial of service attack. (CVE-2019-0203)");
