NVD Description

Note: Versions mentioned in the description apply only to the upstream subversion:1.10/subversion-gnome package and not the subversion:1.10/subversion-gnome package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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. This issue was fixed in mod_dav_svn+mod_authz_svn servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7
