"According to its banner, the version of Apache 1.3.x running on the
remote host is prior 1.3.42. It is, therefore, potentially affected
by an integer overflow vulnerability in the mod_proxy Apache module.
A remote attacker can exploit this to cause a denial of service
condition or to execute arbitrary code.

Note that successful exploitation is possible only on platforms where
sizeof(int) < sizeof(long), such as 64-bit architectures. 

Also note that version 1.3.42 is the final release of Apache 1.3.");
