A use-after-free vulnerability was found in Subversion in the mod_dav_svn Apache HTTP server (HTTPd) module. While looking up path-based authorization (authz) rules, multiple calls to the post_config hook can invalidate cached pointers to object-pools, which Subversion subsequently uses. This issue crashes the single HTTPd worker thread or the entire HTTPd server process, depending on the configuration of the Apache HTTPd server.
