macos-mdnsresponder-upnp-bo (34493) The risk level is classified as HighHigh Risk

Description:

Apple Mac OS X is vulnerable to a buffer overflow in the UPnP IGD (Internet Gateway Device Standardized Device Control Protocol) code of the mDNSResponder implementation. By sending a specially-crafted packet to a vulnerable system, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.

The IBM ISS X-Force analysts have discovered that this vulnerability is only present if the computer has a private ip address per RFC 1918.
