Vulnerable Systems:
* Norton Personal Firewall 2006 version 9.1.0.33
* probably all versions of Norton Personal Firewall 2006 and Norton Internet Security 2006
* possibly older versions of Norton Personal Firewall and Norton Internet Security
Norton insufficiently protects its driver '\Device\SymEvent' against a manipulation by malicious applications and it fails to validate its input buffer. It is possible to open this driver and send arbitrary data to it, which are implicitly believed to be valid. It is possible to assemble the data in the input buffer such that the driver performs an invalid memory operation and crashes the whole operating system. Further impacts of this bug were not examined.
