-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of Symantec Client Security. Authentication is
not required to exploit this vulnerability.

The specific flaw resides in the Alert Originator service, iao.exe,
which listens by default on TCP port 38292. The process blindly copies
user-supplied data to a stack buffer via a memcpy call. By supplying a
specially crafted packet, an attacker can overflow that buffer leading
to arbitrary code execution in the context of the SYSTEM user.

-- Vendor Response:
Symantec has issued an update to correct this vulnerability. More
