CVE-2007-3303 Detail
Modified
This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided. DescriptionApache httpd 2.0.59 and 2.2.4, with the Prefork MPM module, allows local users to cause a denial of service via certain code sequences executed in a worker process that (1) stop request processing by killing all worker processes and preventing creation of replacements or (2) hang the system by forcing the master process to fork an arbitrarily large number of worker processes. NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments. Metrics

Vendor Statements (disclaimer)Official Statement from Red Hat (06/26/2007)Not a vulnerability. In the security model used by Apache httpd, the less-privileged child processes (running as the "apache" user) completely handle the servicing of new connections. Any local user who is able to run arbitrary code in those children is therefore able to prevent new requests from being serviced, by design. Such users will also be able to "simulate" server load and force the parent to create children up to the configured limits, by design. Official Statement from Apache (07/02/2008)In the security model used by Apache httpd, the less-privileged child processes completely handle the servicing of new connections. Any local user who is able to run arbitrary code in those children is therefore able to prevent new requests from being serviced, by design. Such users will also be able to "simulate" server load and force the parent to create children up to the configured limits, by design. A server with untrusted local users must be configured to use a solution like "suexec" if its required to allow the users to execute CGI (etc) scripts.
