According to its version number, the remote version of Apache Web
Server is prone to a local buffer-overflow vulnerability that
affects a configuration file environment variable. This occurs
because the application fails to validate user-supplied string
lengths before copying them into finite process buffers.
An attacker may leverage this issue to execute arbitrary code on
the affected computer with the privileges of the Apache webserver
process.
