Off-by-one error in libxml in Apple Safari before 5.0.6 allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via a crafted web site.

ImageIO in Apple Safari before 5.0.6 on Windows does not properly address re-entrancy issues, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF file.

CFNetwork in Apple Safari before 5.0.6 on Windows does not properly handle an untrusted attribute of a system root certificate, which allows remote web servers to bypass intended SSL restrictions via a certificate signed by a blacklisted certification authority.

Cross-site scripting (XSS) vulnerability in CFNetwork in Apple Safari before 5.0.6 allows remote attackers to inject arbitrary web script or HTML via a crafted text/plain file.

CFNetwork in Apple Safari before 5.0.6 on Windows allows remote web servers to execute arbitrary code by replaying the NTLM credentials of a client user, related to a "credential reflection" issue.

The GPU support functionality in Windows XP does not properly restrict rendering time, which allows remote attackers to cause a denial of service (system crash) via vectors involving WebGL and (1) shader programs or (2) complex 3D geometry, as demonstrated by using Mozilla Firefox or Google Chrome to visit the lots-of-polys-example.html test page in the Khronos WebGL SDK.

The Vector Markup Language (VML) implementation in vgx.dll in Microsoft Internet Explorer 6 through 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, aka "VML Memory Corruption Vulnerability."

Microsoft Internet Explorer 7 through 9 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, aka "HTTP Redirect Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 through 9 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, aka "Selection Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 through 8 does not properly restrict web script, which allows user-assisted remote attackers to obtain sensitive information from a different (1) domain or (2) zone via vectors involving a drag-and-drop operation, aka "Drag and Drop Information Disclosure Vulnerability."

Microsoft Internet Explorer 6 through 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, aka "DOM Modification Memory Corruption Vulnerability."

The Timed Interactive Multimedia Extensions (aka HTML+TIME) implementation in Microsoft Internet Explorer 6 through 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, aka "Time Element Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 through 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, aka "Drag and Drop 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, aka "DOM Manipulation Memory Corruption Vulnerability."

Microsoft Internet Explorer 6 through 9 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, aka "Link Properties Handling Memory Corruption Vulnerability."

Microsoft Internet Explorer 8 does not properly handle content settings in HTTP responses, which allows remote web servers to obtain sensitive information from a different (1) domain or (2) zone via a crafted response, aka "MIME Sniffing Information Disclosure Vulnerability."

Integer underflow in the OLE Automation protocol implementation in VBScript.dll in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows remote attackers to execute arbitrary code via a crafted WMF file, aka "OLE Automation Underflow Vulnerability."

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows local users to gain privileges via a crafted application that triggers a NULL pointer dereference, a different vulnerability than other "Vulnerability Type 2" CVEs listed in MS11-034, aka "Win32k Null Pointer De-reference Vulnerability."

Microsoft Internet Explorer 6, 7, and 8 does not enforce intended domain restrictions on content access, which allows remote attackers to obtain sensitive information or conduct clickjacking attacks via a crafted web site, aka "Frame Tag Information Disclosure Vulnerability."

DNSAPI.dll in the DNS client in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly process DNS queries, which allows remote attackers to execute arbitrary code via (1) a crafted LLMNR broadcast query or (2) a crafted application, aka "DNS Query Vulnerability."
