iDefense Security Advisory 08.07.07 - Remote exploitation of a heap overflow vulnerability in Apple Inc.'s mDNSResponder application may allow attackers to execute arbitrary code with root privileges. The vulnerability exists within the Legacy NAT Traversal code. Unlike the core of the mDNSResponder service, this area of code does not rely on Multicast UDP. It listens on a dynamically allocated Unicast UDP port. The vulnerability occurs when parsing a malformed HTTP request. This results in an exploitable heap overflow. iDefense has confirmed the existence of this vulnerability in Mac OS X version 10.4.10, Server and Workstation, with mDNSResponder version 108.5. Previous versions may also be affected.
