Heap-based buffer overflow in Microsoft Outlook Express 6 and earlier, and Windows Mail for Vista, allows remote Network News Transfer Protocol (NNTP) servers to execute arbitrary code via long NNTP responses that trigger memory corruption.

The URL handling in Shell32.dll in the Windows shell in Microsoft Windows XP and Server 2003, with Internet Explorer 7 installed, allows remote attackers to execute arbitrary programs via invalid “%” sequences in a mailto: or other URI handler, as demonstrated using mIRC, Outlook, Firefox, Adobe Reader, Skype, and other applications. NOTE: this issue might be related to other issues involving URL handlers in Windows systems, such as CVE-2007-3845. There also might be separate but closely related issues in the applications that are invoked by the handlers.

Buffer overflow in Microsoft DirectShow in Microsoft DirectX 7.0 through 10.0 allows remote attackers to execute arbitrary code via a crafted (1) WAV or (2) AVI file.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via unspecified vectors involving memory corruption from an unhandled error.

Microsoft Internet Explorer 5.01 through 7 allows remote attackers to spoof the URL address bar and other “trust UI” components via unspecified vectors, a different issue than CVE-2007-1091 and CVE-2007-3826.
