Title: Apache HTTP Server Mod_Proxy Denial of Service Vulnerability
Severity: MODERATE
Description:
The Apache mod_proxy module is prone to a denial-of-service vulnerability.
The issue occurs because the software fails to properly handle 'date' headers in the 'ap_proxy_date_canon()' function of 'proxy_util.c'. This could cause a buffer overflow.
If reverse proxy is enabled, an attacker can exploit this issue by sending a specially crafted request. If forward proxy is configured, the attacker must entice an unsuspecting victim into visiting a malicious site using the proxy.
A successful exploit of this issue could lead to denial-of-service conditions if the server is using a multithreaded Multi-Processing Module (MPM). Although this issue occurs because a buffer is overflowed, arbitrary code execution is not believed to be possible.
