sysplant.sys in the Manager component in Symantec Endpoint Protection (SEP) before 12.1.6 allows local users to cause a denial of service (blocked system shutdown) by triggering an unspecified deadlock condition.

The \Device\SymEvent driver in Symantec Norton Personal Firewall 2006 9.1.1.7, and possibly other products using symevent.sys 12.0.0.20, allows local users to cause a denial of service (system crash) via invalid data, as demonstrated by calling DeviceIoControl to send the data, a reintroduction of CVE-2006-4855.

SPBBCDrv.sys in Symantec Norton Personal Firewall 2006 9.1.0.33 and 9.1.1.7 does not validate certain arguments before being passed to hooked SSDT function handlers, which allows local users to cause a denial of service (crash) or possibly execute arbitrary code via crafted arguments to the (1) NtCreateMutant and (2) NtOpenEvent functions. NOTE: it was later reported that Norton Internet Security 2008 15.0.0.60, and possibly other versions back to 2006, are also affected.

GEAR Software CD DVD Filter driver (aka GEARAspiWDM.sys), as used in Symantec Backup Exec System Recovery 8.5 and BESR 2010, Symantec System Recovery 2011, Norton 360, and Norton Ghost, allows local users to cause a denial of service (system crash) via unspecified vectors.
