The Apache HTTP Server, commonly referred to as Apache, is a popular open source web server software. mod_isapi is a core module of the Apache package that implements the Internet Server extension API. The extension allows Apache to serve Internet Server extensions (ISAPI .dll modules) for Microsoft Windows based hosts. By sending a specially crafted request followed by a reset packet it is possible to trigger a vulnerability in Apache mod_isapi that will unload the target ISAPI module from memory. However function pointers still remain in memory and are called when

published ISAPI functions are referenced. This results in a dangling pointer vulnerability.
OpenBSD's PF is prone to a remote denial-of-service vulnerability.

Exploiting this issue allows remote attackers to cause a kernel panic on affected computers, denying further service to legitimate users.



This update improves reliability in Impact 10.
This module exploits a buffer overflow vulnerability in the mDNSResponder service running on certain versions of Apple Mac OS X. The vulnerability is exploited remotely by sending a specially crafted UPnP Internet Gateway Device (IGD) packet and installing an agent.

This update adds port parameter.
