Arrow  Advisory Content :  

Hello,

I would like to inform you about a vulnerability in Norton Personal
Firewall.

Description:

Norton insufficiently protects its driver 'DeviceSymEvent' 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.

Vulnerable software:

* 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

More details and a proof of concept including source code is available
