Details

Subversion's modauthzsvn 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. This issue was fixed in moddavsvn+modauthzsvn servers 1.14.1 and moddavsvn+modauthzsvn servers 1.10.7
