[PLSA 2009-55] Ntp: Buffer Overflow

Summary

Apple discovered a stack-based buffer overflow in the ntpq program.

Description

When the ntpq program is used to request peer information from a remote time server, a maliciously crafted response may lead to an unexpected application termination or arbitrary code execution.

The buffer overflow is limited to two bytes, so a code execution impact is unlikely, but this is dependent on the stack layout generated by cc.
