Internet Explorer, with a security setting below Medium, allows remote attackers to execute arbitrary commands via a malicious web page that uses the FileSystemObject ActiveX object.

The Microsoft Java Virtual Machine allows a malicious Java applet to execute arbitrary commands outside of the sandbox environment.

Microsoft Internet Explorer 5.01 SP4, 6, and 6 SP1 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 6, 6 SP1, 7, and 8 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-2530 and CVE-2009-2531.

Buffer overflow in Microsoft Internet Explorer and Explorer on Windows XP SP1, WIndows 2000, Windows 98, and Windows Me may allow remote malicious servers to cause a denial of service (application crash) and possibly execute arbitrary code via long share names, as demonstrated using Samba.

Use-after-free vulnerability in the CRecalcProperty function in mshtml.dll in Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code by calling the setExpression method and then modifying the outerHTML property of an HTML element, one variant of "Uninitialized Memory Corruption Vulnerability."
