Package        : subversion
Version        : 1.9.5-1+deb9u6
CVE ID         : CVE-2020-17525

One security issue has been discovered in subversion:


    Subversion's mod_authz_svn module will crash if the server is using
    in-repository authz rules with the AuthzSVNReposRelativeAccessFile
    option and a client sends a request for a non-existing repository URL.
    This can lead to disruption for users of the service.

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your subversion packages.
