Apple Mac OS X may be vulnerable to privilege escalation via the Mach exception ports in the kernel. This vulnerability may allow a local user to execute arbitrary code with elevated privileges.
Mach 3.0 is an open source microkernel used by Mac OS X that provides memory management, memory protection, process scheduling, and interprocess communication services. According to Apple Security Update 2006-006:
An error handling mechanism in the kernel, known as Mach exception ports, provides the ability to control programs when certain types of errors are encountered. Malicious local users could use this mechanism to execute arbitrary code in privileged programs if an error is encountered.
A local user may be able to execute arbitrary code with elevated privileges.
This issue was reported in Apple Security Update 2006-006. Apple credits Dino Dai Zovi of Matasano Security for reporting this issue.
