Description

A local overflow exists in Apache. The mod_rewrite module fails to handle regular expressions containing more than 9 captures (stored strings matching a particular pattern) resulting in a buffer overflow. With a specially crafted request, an attacker can execute arbitrary code or cause a denial of service resulting in a loss of integrity and/or confidentiality.
