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.

The SymTDI device driver (SYMTDI.SYS) in Symantec Norton Personal Firewall 2006 9.1.1.7 and earlier, Internet Security 2005 and 2006, AntiVirus Corporate Edition 3.0.x through 10.1.x, and other Norton products, allows local users to cause a denial of service (system crash) by sending crafted data to the driver's \Device file, which triggers invalid memory access, a different vulnerability than CVE-2006-4855.

Multiple buffer overflows in the SupportSoft (1) SmartIssue (tgctlsi.dll) and (2) ScriptRunner (tgctlsr.dll) ActiveX controls, as used by Symantec Automated Support Assistant and Norton AntiVirus, Internet Security, and System Works 2006, allows remote attackers to execute arbitrary code via a crafted HTML message.

Unspecified vulnerability in an ActiveX control used in Symantec Automated Support Assistant, as used in Norton AntiVirus, Internet Security, and System Works 2005 and 2006, allows user-assisted remote attackers to obtain sensitive information via unspecified vectors.

Stack-based buffer overflow in an ActiveX control used in Symantec Automated Support Assistant, as used in Norton AntiVirus, Internet Security, and System Works 2005 and 2006, allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

The \Device\SymEvent driver in Symantec Norton Personal Firewall 2006 9.1.0.33, and other versions of Norton Personal Firewall, Internet Security, AntiVirus, SystemWorks, Symantec Client Security SCS 1.x, 2.x, 3.0, and 3.1, Symantec AntiVirus Corporate Edition SAVCE 8.x, 9.x, 10.0, and 10.1, Symantec pcAnywhere 11.5 only, and Symantec Host, allows local users to cause a denial of service (system crash) via invalid data, as demonstrated by calling DeviceIoControl to send the data.
