Firefox before 1.0 does not properly distinguish between user-generated and synthetic click events, which allows remote attackers to use Javascript to bypass the file download prompt when the user uses the Alt-click feature.

Safari 1.2.4 on Mac OS X 10.3.6 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.

Opera 7.54 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows untrusted Javascript code to read and write to the clipboard, and possibly obtain sensitive information, via script-generated events such as Ctrl-Ins.

Internet Explorer 6.0 on Windows XP SP2 allows remote attackers to execute arbitrary code by using the "Related Topics" command in the Help ActiveX Control (hhctrl.ocx) to open a Help popup window containing the PCHealth tools.htm file in the local zone and injecting Javascript to be executed, as demonstrated using "writehta.txt" and the ADODB recordset, which saves a .HTA file to the local system, aka the "HTML Help ActiveX control Cross Domain Vulnerability."

Internet Explorer 6 allows remote attackers to bypass the popup blocker via the document object model (DOM) methods in the DHTML Dynamic HTML (DHTML) Editing Component (DEC) and Javascript that calls showModalDialog.

Microsoft Internet Explorer allows remote attackers to cause a denial of service (application crash from memory consumption), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.

Firefox and Mozilla allow remote attackers to cause a denial of service (application crash from memory consumption), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.

Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory.

Integer overflow in the InitialDirContext in Java Runtime Environment (JRE) 1.4.2, 1.5.0 and possibly other versions allows remote attackers to cause a denial of service (Java exception and failed DNS requests) via a large number of DNS requests, which causes the xid variable to wrap around and become negative.

ZoneAlarm and ZoneAlarm Pro before 5.5.062, with ad-blocking enabled, allows remote web sites to cause a denial of service (application instability or system hang) via certain JavaScript.

The Apple Java plugin, as used in Netscape 7.1 and 7.2, Mozilla 1.7.2, and Firefox 0.9.3 on MacOS X 10.3.5, when tabbed browsing is enabled, does not properly handle SetWindow(NULL) calls, which allows Java applets from one tab to draw to other tabs and facilitates phishing attacks that spoof tabs.

The Javascript engine in Opera 7.23 allows remote attackers to cause a denial of service (crash) by creating a new Array object with a large size value, then writing into that array.

Multiple cross-site scripting (XSS) vulnerabilities in (1) imagezoom.asp or (2) recommend.asp in Q-Shop allow remote attackers to execute arbitrary script and steal the user session ID via Javascript in a URL.

Cross-site scripting (XSS) vulnerability in Custva.asp in EarlyImpact ProductCart allows remote attackers to inject arbitrary Javascript via the redirectUrl parameter.

Unknown vulnerability in Sun Java System Web Server 6.0 SP7 and earlier and 6.1 SP1 and earlier, and Application Server 7 Update 4 and earlier, allows remote attackers to cause a denial of service (crash) via a malformed client certificate.

Microsoft Internet Explorer 6 allows remote attackers to spoof the address bar to facilitate phishing attacks via Javascript that uses an invalid URI, modifies the Location field, then uses history.back to navigate to the previous domain, aka NullyFake.

Buffer overflow in IBM Lotus Notes 6.5.x before 6.5.3 and 6.0.x before 6.0.5 allows remote attackers to cause a denial of service (crash) via unknown vectors related to Java applets, as identified by KSPR62F4KN.

Multiple unknown vulnerabilities in IBM Lotus Notes 6.5.x before 6.5.4 and 6.0.x before 6.0.5 have unknown impact and attack vectors, related to Java applets, as identified by (1) KSPR5YS6GR and (2) KSPR62F4D3.

ColdFusion MX 6.1 and 6.1 J2EE allows local users to bypass sandbox security restrictions and obtain sensitive information by using Java reflection methods to access trusted Java objects without using the CreateObject function or cfobject tag.
