Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.6.x before 3.6.11 and Thunderbird 3.1.x before 3.1.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.14, Thunderbird before 3.0.9, and SeaMonkey before 2.0.9 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The browser-plugin implementation in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1 allows remote attackers to arguments to the RecordClip method, which allows remote attackers to download an arbitrary program onto a client machine, and execute this program, via a " (double quote) in an argument to the RecordClip method, aka "parameter injection."

The browser in Research In Motion (RIM) BlackBerry Device Software 5.0.0.593 Platform 5.1.0.147 on the BlackBerry 9700 does not properly restrict cross-domain execution of JavaScript, which allows remote attackers to bypass the Same Origin Policy via vectors related to a window.open call and an IFRAME element. NOTE: some of these details are obtained from third party information.

Microsoft Windows Media Player (WMP) 9 through 12 does not properly deallocate objects during a browser reload action, which allows user-assisted remote attackers to execute arbitrary code via crafted media content referenced in an HTML document, aka "Windows Media Player Memory Corruption Vulnerability."

Cross-site scripting (XSS) vulnerability in Flock Browser 3.x before 3.0.0.4114 allows remote attackers to inject arbitrary web script or HTML via a crafted RSS feed.

Cross-site scripting (XSS) vulnerability in Flock Browser 3.0.0.3989 allows remote attackers to inject arbitrary web script or HTML via a crafted bookmark.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Unspecified vulnerability in an ActiveX control in the Internet Explorer (IE) plugin in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows has unknown impact and attack vectors related to "multiple browser windows."

Stack-based buffer overflow in the browser plugin in Novell iPrint Client before 5.42 allows remote attackers to execute arbitrary code via a long operation parameter.

Buffer overflow in the browser plugin in Novell iPrint Client before 5.42 allows remote attackers to execute arbitrary code by using EMBED elements to pass parameters with long names.

A certain ActiveX control in ienipp.ocx in the browser plugin in Novell iPrint Client before 5.42 does not properly restrict the set of files to be deleted, which allows remote attackers to cause a denial of service (recursive file deletion) via unspecified vectors related to a "logic flaw" in the CleanUploadFiles method in the nipplib.dll module.

The ienipp.ocx ActiveX control in the browser plugin in Novell iPrint Client before 5.42 does not properly validate the debug parameter, which allows remote attackers to execute arbitrary code or cause a denial of service (stack memory corruption) via a parameter value with a crafted length, related to the ExecuteRequest method.

The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0 SP1, 2.0 SP2, 3.5, 3.5 SP1, and 3.5.1, and Microsoft Silverlight 2 and 3 before 3.0.50611.0 on Windows and before 3.0.41130.0 on Mac OS X, does not properly handle interfaces and delegations to virtual methods, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka "Microsoft Silverlight and Microsoft .NET Framework CLR Virtual Method Delegate Vulnerability."

js/src/jstracer.cpp in the browser engine in Mozilla Firefox 3.6.x before 3.6.7 and Thunderbird 3.1.x before 3.1.1 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) propagation of deep aborts in the TraceRecorder::record_JSOP_BINDNAME function, (2) depth handling in the TraceRecorder::record_JSOP_GETELEM function, and (3) tracing of out-of-range arguments in the TraceRecorder::record_JSOP_ARGSUB function.
