Vulnerability Note VU#354486

Original Release Date: 2005-05-16 | Last Revised: 2005-05-17


Apple Mac OS X Server NeST tool contains a vulnerability in the processing of command line arguments that could allow an attacker to execute arbitrary code.


NeST is the NetInfo Setup Tool for Apple Mac OS X Server. There is a buffer overflow vulnerability in the way NeST performs bounds checking on command line arguments. By supplying the -target command line parameter with an overly long string of characters, a local user could execute arbitrary code on the system with privileges of the NeST process.

Please note that NeST executes with root privileges.


A local user could execute arbitrary code with privileges of the NeST process, possibly root.
