mod_cgi in Apache 2.0.39 and 2.0.40 allows local users and possibly remote attackers to cause a denial of service (hang and memory consumption) by causing a CGI script to send a large amount of data to stderr, which results in a read/write deadlock between httpd and the CGI script.

Security readout for executives and security teams

This is an old Apache HTTP Server denial-of-service issue. A vulnerable server can hang and consume memory when CGI error output is mishandled. Business impact is service availability, not confirmed data theft. It matters mainly for legacy Apache 2.0.39 or 2.0.40 systems still running CGI. Exposure is most likely on legacy Apache 2.0.39 or 2.0.40 deployments with mod_cgi enabled and CGI scripts available. Modern Apache deployments or servers without CGI are less likely to be affected, but the bundle does not provide complete product inventory guidance. Treat this as a legacy availability risk. It is not KEV-listed and has no supplied CVSS score, but affected internet-facing or business-critical CGI servers should be retired, upgraded, or isolated because a hang can interrupt service. Mitigation focus: Inventory Apache HTTP Server versions and identify any 2.0.39 or 2.0.40 instances.; Check Apache or operating-system vendor guidance for the corrected mod_cgi behavior.; Disable or restrict CGI functionality where it is not operationally required..
