CVE-2002-1850 Information

Description

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.
