• Apache 2.0.39/40 - Oversized STDERR Buffer Denial of Service2002-09-24 · dos · linux · Verified

Impact

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.
