HTTP: Apache Subversion mod_authz_svn AuthzSVNReposRelativeAccessFile Null Pointer Dereference
This signature detects attempts to exploit a known vulnerability against the mod_authz_svn Apache HTTPD module of Apache Subversion. A successful attack can result in a denial-of-service condition.
Extended Description
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
