Apple Safari on Mac OS X, and before 3.1.2 on Windows, does not prompt the user before downloading an object that has an unrecognized content type, which allows remote attackers to place malware into the (1) Desktop directory on Windows or (2) Downloads directory on Mac OS X, and subsequently allows remote attackers to execute arbitrary code on Windows by leveraging an untrusted search path vulnerability in (a) Internet Explorer 7 on Windows XP or (b) the SearchPath function in Windows XP, Vista, and Server 2003 and 2008, aka a "Carpet Bomb" and a "Blended Threat Elevation of Privilege Vulnerability," a different issue than CVE-2008-1032. NOTE: Apple considers this a vulnerability only because the Microsoft products can load application libraries from the desktop and, as of 20080619, has not covered the issue in an advisory for Mac OS X.

Unspecified vulnerability in the kernel in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, through Vista SP1, and Server 2008 allows local users to execute arbitrary code via unknown vectors related to improper input validation. NOTE: it was later reported that one affected function is NtUserFnOUTSTRING in win32k.sys.

The setRequestHeader method of the XMLHttpRequest object in Microsoft Internet Explorer 5.01, 6, and 7 does not block dangerous HTTP request headers when certain 8-bit character sequences are appended to a header name, which allows remote attackers to (1) conduct HTTP request splitting and HTTP request smuggling attacks via an incorrect Content-Length header, (2) access arbitrary virtual hosts via a modified Host header, (3) bypass referrer restrictions via an incorrect Referer header, and (4) bypass the same-origin policy and obtain sensitive information via a crafted request header.

Microsoft XML Core Services (MSXML) 3.0 through 6.0 allows remote attackers to execute arbitrary code via the substringData method on a (1) TextNode or (2) XMLDOM object, which causes an integer overflow that leads to a buffer overflow.
