This signature is provided as a supplement to S13 signatures 3403 and 3501 to better detect any attacks. It will be incorporated into a future signature update. Listed below is a sample screenshot of the output of the SigWizMenu tool. Please refer to the sensor Release Notes for instructions on how to use the SigWizMenu tool to add a custom signature.
Re: Additional Custom Signature for the SysV /bin/login Overflow
All custom signatures are included in later releases. Once a signature update is release, all prior custom signatures should be covered in the release. The custom signature releases are used only for signatures that have serious 0-day implications and cannot wait for the usual two week release. Those signatures then make it into the next signature update.
