The Microsoft Windows LoadImage API routine is vulnerable to an integer overflow that may allow a remote attacker to execute arbitrary code on a vulnerable system.
The LoadImage API routine is used to load an image from a file on Microsoft Windows platforms. The LoadImage API is included part of the USER 32 library. A lack of input validation on user supplied input to the LoadImage API routine may allow an integer overflow to occur. If a remote attacker supplies a specially crafted image file to a vulnerable system, that attacker may be able to trigger the integer overflow to compromise that system.
According to public reports, many Microsoft Windows are affected. However, reports also indicate Windows XP with Service Pack 2 is not vulnerable, but we have not confirmed this.
If a remote attacker can persuade a user to access a specially crafted image file, the attacker may be able to execute arbitrary code on that user's system, possibly with elevated privileges. Potentially any operation that displays an image could trigger exploitation; for instance, browsing the file system, reading HTML email, or browsing websites.
