CVE-2018-11782
Ace Olszowka reported that the Subversion's svnserve server process may exit when a well-formed read-only request produces a particular answer, leading to a denial of service.
CVE-2019-0203
Tomas Bortoli reported that the Subversion's svnserve server process may exit when a client sends certain sequences of protocol commands. If the server is configured with anonymous access enabled this could lead to a remote unauthenticated denial of service.
For the oldstable distribution (stretch), these problems have been fixed in version 1.9.5-1+deb9u4.
For the stable distribution (buster), these problems have been fixed in version 1.10.4-1+deb10u1.
We recommend that you upgrade your subversion packages.
For the detailed security status of subversion please refer to its security tracker page at: [link moved to references]");
