A buffer overflow vulnerability in the Apple Mac OS X bootp daemon may allow an attacker to execute arbitrary code on an affected system.
bootpd
The bootp daemon (bootpd
) is used to send clients network and IP address configuration settings. It can also work in combination with a TFTP server to transfer an operating system image to diskless clients.
The Problem
There is a stack-based buffer overflow in bootpd's
request processing. An attacker may be able to create a specially crafted bootp
request, that when sent to the server running bootpd
, would trigger the overflow.
Note that bootpd
is not enabled by default on any supported version of Mac OS X.
An attacker may be able to execute arbitrary code with root
privileges on the affected system.
Upgrade
Apple has addressed this issue in Security Update 2006-004. Refer to Apple’s Security Update site for more information.
Do not Enable bootpd
Do not enable bootpd
unless you need the service to run. The command “ps -aux | grep
”
can be used to check if the bootpd process is running.
Restrict Access
Restrict access to the bootpd
server to trusted hosts only. More details on configuring bootpd
can be found in the Apple OS X Server System Image Administration Guide.
