The Symantec ESM manager and agent will hang, with nearly 100% CPU usage, after some network scans have contacted one of the ESM network ports. ESM misinterprets this information and becomes non-responsive. This leads to a Denial of Service condition.

A restart of the manager or agent is required to restore ESM to a functional state.

Symantec Response
Symantec has released downloadable automated and manual fixes for all supported vulnerable ESM managers and agents (see the list above).

To date, Symantec is not aware of any reported attempts to exploit this vulnerability.

For more information about installing or updating ESM components see the Symantec Enterprise Security Manager Installation Guide.
