Description:
Braden Thomas has reported a vulnerability in iSync, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a boundary error in the handling of the "-v" and "-a" command line options. This can be exploited to cause a buffer overflow by supplying an overly long argument (over 4096 bytes).
Successful exploitation allows execution of arbitrary code with the privileges of the mRouter application.
The vulnerability has been reported in Mac OS X 10.3.7 and prior.
Solution:
Apply Security Update 2005-004.
