Technical details

A heap-based buffer overflow vulnerability exists in Microsoft Windows Imaging Component, allowing remote code execution. The vulnerability can be exploited over the network without requiring user authentication or interaction, making it a critical network-reachable attack vector. An attacker can craft malicious image data that, when processed by the component, triggers the buffer overflow and achieves arbitrary code execution with the privileges of the process handling the image. A patch is available from Microsoft.
