AV:L/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Apple Mac OS X versions 10.4 through 10.5.1

Description The issue is related to an integer overflow in the load threadstack function within the Mach-O loader of the xnu kernel. This can be exploited by local users through a crafted Mach-O binary, leading to a denial of service in the form of an infinite loop.

Recommendations For Apple Mac OS X versions 10.4 through 10.5.1, consider applying configuration changes to restrict the execution of crafted Mach-O binaries until a fix is available. As a temporary workaround, restrict access to the Mach-O loader to minimize the risk of exploitation.
