Description:
A vulnerability has been reported in the Apache mod_proxy module, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to the improper handling of date headers within the "ap_proxy_date_canon()" function in proxy_util.c. This can be exploited to cause a DoS by sending specially crafted requests to the affected server.
Successful exploitation results in a crash if a threaded Multi-Processing Module is used on servers where a reverse or forward proxy is configured.
The vulnerability is reported in Apache 2.0.x versions 2.0.59 and prior, and Apache 2.2.x versions 2.2.4 and prior.
