CVE-2012-0021: Input Validation
First published: Fri Jan 27 2012(Updated: )
A flaw [1] was found in mod_log_config. If an administrator configured the "%{cookiename}C" log format string to be used, a remote attacker could send a specific cookie which would cause a crash. This crash would only be a denial of service if using a threaded MPM (such as event or worker). Note that Red Hat Enterprise Linux and Fedora use the prefork MPM by default. This will be fixed upstream [2] in 2.2.22 and affects versions 2.2.17 up to and including 2.2.21.

This issue did not affect the versions of httpd as shipped with Red Hat Enterprise Linux 4, 5, or 6.
