We would like to inform you about a vulnerability in Symantec Norton products.
Symantec Norton Personal Firewall hooks many functions in SSDT and in at least two cases it fails to validate arguments
that come from the user mode. User calls to NtCreateMutant and NtOpenEvent with invalid argument values can cause system
crashes because of errors in Norton driver SPBBCDrv.sys. Further impacts of this bug (like arbitrary code execution in
the kernel mode) were not examined.
* Norton Personal Firewall 2006 version 22.214.171.124
* Norton Personal Firewall 2006 version 126.96.36.199
* probably all versions of Norton Personal Firewall 2006, Norton Internet Security 2006 and other products that use
* possibly older versions of Norton Personal Firewall and Norton Internet Security
