Apache HTTP Server mod_proxy reverse proxy issue

The reverse proxy feature (mod_proxy) has a new vulnerability.  If pattern matching is used, a crafted attack (using invalid inputs - even though this does not involve SQL the "Little Bobby Tables" XKCD comes to mind again, for like the 3rd time this week ! ) can expose information on internal hosts.

Full details (and remediation) here ==> http://seclists.org/fulldisclosure/2011/Oct/232

Patch is available for 2.2.21 here==> http://www.apache.org/dist/httpd/patches/apply_to_2.2.21/

the CVE is pretty sparse, but look for more content soon ==> CVE-2011-3368
