Description Murray McAllister 2014-12-15 05:11:33 UTC

If an authorization script for LuaAuthzProvider were provided in the configuration multiple times, only the arguments of the last specification were used when invoking the script. This could lead to scripts being invoked with unexpected arguments.

Further details are available in the thread of the original report and bug:

https://issues.apache.org/bugzilla/show_bug.cgi?id=57204

Upstream fix:

https://github.com/apache/httpd/commit/3f1693d558d0758f829c8b53993f1749ddf6ffcb

This affects Apache HTTP Server versions 2.3 and later (such as what is shipped in Red Hat Enterprise Linux 7), as mod_lua is not available in earlier releases. Note that support for LuaAuthzProvider is experimental.
