Use-after-free vulnerability in mstime.dll in Microsoft Internet Explorer 8 allows remote attackers to execute arbitrary code via vectors related to the TIME2 behavior, the CTimeAction object, and destruction of markup, leading to memory corruption, aka "HTML Object Memory Corruption Vulnerability."

Cross-domain vulnerability in Microsoft Internet Explorer 6, 6 SP1, 7, and 8 allows user-assisted remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via a crafted HTML document in a situation where the client user drags one browser window across another browser window, aka "HTML Element Cross-Domain Vulnerability."

Unspecified vulnerability in Internet Explorer 8 on Microsoft Windows 7 allows remote attackers to execute arbitrary code via unknown vectors, possibly related to a use-after-free issue, as demonstrated by Peter Vreugdenhil during a Pwn2Own competition at CanSecWest 2010.

Heap-based buffer overflow in Internet Explorer 8 on Microsoft Windows 7 allows remote attackers to discover the base address of a Windows .dll file, and possibly have unspecified other impact, via unknown vectors, as demonstrated by Peter Vreugdenhil during a Pwn2Own competition at CanSecWest 2010.

Microsoft Internet Explorer 5.01 SP4, 6, 6 SP1, 7, and 8 does not prevent rendering of non-HTML local files as HTML documents, which allows remote attackers to bypass intended access restrictions and read arbitrary files via vectors involving JavaScript exploit code that constructs a reference to a file://127.0.0.1 URL, aka the dynamic OBJECT tag vulnerability, as demonstrated by obtaining the data from an index.dat file, a variant of CVE-2009-1140 and related to CVE-2008-1448.

Microsoft Internet Explorer 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-2009-3671, CVE-2009-3674, and CVE-2010-0246.

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 "HTML Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 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-2009-3671, CVE-2009-3674, and CVE-2010-0245.

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.

The URL validation functionality in Microsoft Internet Explorer 5.01, 6, 6 SP1, 7 and 8, and the ShellExecute API function in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2, does not properly process input parameters, which allows remote attackers to execute arbitrary local programs via a crafted URL, aka "URL Validation Vulnerability."
