Description:
eEye Digital Security has reported a vulnerability in Symantec Client Security and Symantec AntiVirus Corporate Edition, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the remote management interface when processing "COM_FORWARD_LOG" commands. This can be exploited to cause a stack-based buffer overflow via a specially crafted "COM_FORWARD_LOG" command sent to port 2967/tcp.

Successful exploitation allows execution of arbitrary code with SYSTEM privileges.

Solution:
Apply patches (see patch matrix in vendor advisory).
