Description
Buffer overflow in the shared_region_make_private_np function in vm/vm_unix.c in Mac OS X 10.4.6 and earlier allows local users to execute arbitrary code via (1) a small range count, which causes insufficient memory allocation, or (2) a large number of ranges in the shared_region_make_private_np_args parameter.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
