Buffer overflow in an ActiveX control (SYMLTCOM.dll) in Symantec N360 1.0 and 2.0; Norton Internet Security, AntiVirus, SystemWorks, and Confidential 2006 through 2008; and Symantec Client Security 3.0.x before 3.1 MR9, and 3.1.x before MR9; allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors. NOTE: this is only a vulnerability if the attacker can "masquerade as an authorized site."

Unspecified vulnerability in Symantec Norton AntiVirus 2005 through 2008; Norton Internet Security 2005 through 2008; AntiVirus Corporate Edition 9.0 before MR7, 10.0, 10.1 before MR8, and 10.2 before MR3; and Client Security 2.0 before MR7, 3.0, and 3.1 before MR8; when Internet Email Scanning is installed and enabled, allows remote attackers to cause a denial of service (CPU consumption and persistent connection loss) via unknown attack vectors.

Multiple cross-site scripting (XSS) vulnerabilities in ccLgView.exe in the Symantec Log Viewer, as used in Symantec AntiVirus (SAV) before 10.1 MR8, Symantec Endpoint Protection (SEP) 11.0 before 11.0 MR1, Norton 360 1.0, and Norton Internet Security 2005 through 2008, allow remote attackers to inject arbitrary web script or HTML via a crafted e-mail message, related to "two parsing errors."

The ActiveDataInfo.LaunchProcess method in the SymAData.ActiveDataInfo.1 ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, does not properly determine the location of the AutoFix Tool, which allows remote attackers to execute arbitrary code via a remote (1) WebDAV or (2) SMB share.

Stack-based buffer overflow in the AutoFix Support Tool ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products, including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, allows remote attackers to execute arbitrary code via a long argument to the GetEventLogInfo method. NOTE: some of these details are obtained from third party information.

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.
