    CVE-2002-1850

    Published: 31 Dec 2002Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
