Stack-based buffer overflow in the OpenType Compact Font Format (aka OTF or CFF) driver 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 crafted parameter values in an OpenType font, aka "OpenType Font Stack Overflow Vulnerability."

fxscover.exe in the Fax Cover Page Editor 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 parse FAX cover pages, which allows remote attackers to execute arbitrary code via a crafted .cov file, aka "Fax Cover Page Editor Memory Corruption Vulnerability."

The x86 JIT compiler in Microsoft .NET Framework 2.0 SP2, 3.5 SP1, 3.5.1, and 4.0 does not properly compile function calls, 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 ".NET Framework Stack Corruption Vulnerability."

The default configuration of Microsoft Windows 7 immediately prefers a new IPv6 and DHCPv6 service over a currently used IPv4 and DHCPv4 service upon receipt of an IPv6 Router Advertisement (RA), and does not provide an option to ignore an unexpected RA, which allows remote attackers to conduct man-in-the-middle attacks on communication with external IPv4 servers via vectors involving RAs, a DHCPv6 server, and NAT-PT on the local network, aka a "SLAAC Attack." NOTE: it can be argued that preferring IPv6 complies with RFC 3484, and that attempting to determine the legitimacy of an RA is currently outside the scope of recommended behavior of host operating systems

Unspecified vulnerability in Microsoft Internet Explorer 8 on Windows 7 allows remote attackers to bypass Protected Mode and create arbitrary files by leveraging access to a Low integrity process, as demonstrated by Stephen Fewer as the third of three chained vulnerabilities during a Pwn2Own competition at CanSecWest 2011.

Unspecified vulnerability in Microsoft Internet Explorer 8 on Windows 7 allows remote attackers to execute arbitrary code via unknown vectors, as demonstrated by Stephen Fewer as the second of three chained vulnerabilities during a Pwn2Own competition at CanSecWest 2011.

Microsoft Internet Explorer 6, 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, as demonstrated by Stephen Fewer as the first of three chained vulnerabilities during a Pwn2Own competition at CanSecWest 2011, aka "Object Management Memory Corruption Vulnerability."

Buffer overflow in Fax4Decode in LibTIFF 3.9.4 and possibly other versions, as used in ImageIO in Apple iTunes before 10.2 on Windows and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF Internet Fax image file that has been compressed using CCITT Group 4 encoding, related to the EXPAND2D macro in libtiff/tif_fax3.h. NOTE: some of these details are obtained from third party information.

Buffer overflow in LibTIFF 3.9.4 and possibly other versions, as used in ImageIO in Apple iTunes before 10.2 on Windows and other products, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF image with JPEG encoding.
