fcgid_spawn_ctl.c in the mod_fcgid module 2.3.6 for the Apache HTTP Server does not recognize the FcgidMaxProcessesPerClass directive for a virtual host, which makes it easier for remote attackers to cause a denial of service (memory consumption) via a series of HTTP requests that triggers a process count higher than the intended limit.

CVE-2012-1181 mod_fcgid 2.3.6 does not respect configured FcgidMaxProcessesPerClass in VirtualHost
Daniel Kahn Gillmor [email protected] reports:
Version 2.3.6 of mod-fcgid (the current published version from ASF according to [0]) has a known problem that FcgidMaxProcessesPerClass directives are not honored when they appear inside a VirtualHost stanza.
This is presents a risk for a denial of service because it means that a remote attacker can violate the intent of the admin and overwhelm the server running fcgid.
Could a CVE be assigned for this vulnerability?
If the admin declares that a given virtualhost should be limited to X fastcgi processes (often in order to constrain RAM usage by the vhost), any remote user can issue X+1 (or 10X, or whatever) concurrent GET requests, which
