Microsoft Windows OleLoadPicture Bitmap Heap Corruption Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the OleLoadPicture function. User-supplied data is used to calculate a buffer length for allocation, and if the image is a bitmap, the function can then write beyond the buffer boundary. An attacker can leverage this functionality to execute arbitrary code in the context of the user.
