A vulnerability was discovered and corrected in subversion:

authz.c in the mod_dav_svn module for the Apache HTTP Server,
as distributed in Apache Subversion 1.5.x before 1.5.8 and 1.6.x
before 1.6.13, when SVNPathAuthz short_circuit is enabled, does not
properly handle a named repository as a rule scope, which allows
remote authenticated users to bypass intended access restrictions
via svn commands (CVE-2010-3315).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
