CVE-2005-4625 in Catalyst Driver
Summary
by MITRE
Drivers for certain display adapters, including (1) an unspecified ATI driver and (2) an unspecified Intel driver, might allow remote attackers to cause a denial of service (system crash) via a large JPEG image, as demonstrated in Internet Explorer using stoopid.jpg with a width and height of 9999999.

This vulnerability represents a critical denial of service flaw affecting graphics drivers from major hardware vendors including ATI and Intel. The issue manifests when these drivers process malformed JPEG images with extremely large dimensions, specifically demonstrated with a file named stoopid.jpg measuring 9999999 pixels in both width and height. The vulnerability stems from insufficient input validation within the graphics processing pipeline where drivers fail to properly handle oversized image data structures. When Internet Explorer attempts to render such an image, the driver processes the malformed dimensions without proper bounds checking, leading to memory allocation failures and system instability. The flaw operates at the kernel level within graphics driver components, making it particularly dangerous as it can trigger system crashes regardless of user privileges. This vulnerability aligns with CWE-129, Input Validation, and CWE-125, Out-of-bounds Read, as the drivers fail to validate image dimensions before processing them. The attack vector is remote and requires no special privileges, making it highly exploitable through web-based attacks. From an operational perspective, this vulnerability creates significant risk for enterprise environments where users may inadvertently encounter malicious JPEG files in web content, email attachments, or file sharing systems. The system crash resulting from this vulnerability can be persistent and difficult to recover from without manual intervention, potentially causing extended downtime for affected systems. The impact extends beyond simple service disruption to include potential data loss scenarios where users may lose unsaved work during system crashes. This vulnerability demonstrates how graphics processing components can become attack surfaces for denial of service attacks, particularly when dealing with image rendering in web browsers. The flaw is particularly concerning because it affects widely deployed hardware drivers and can be triggered through common web browsing activities. Security professionals should consider this vulnerability when assessing risk in environments with older graphics drivers, as the issue may remain exploitable even in systems where other security measures are in place. The vulnerability also highlights the importance of proper bounds checking in graphics processing libraries and the need for comprehensive testing of image processing components against malformed inputs. From a threat modeling perspective, this vulnerability can be categorized under the ATT&CK technique T1499.004, Network Denial of Service, as it enables attackers to cause system instability through network-delivered content. The vulnerability serves as a reminder of the critical importance of driver security in operating system architectures and the potential for seemingly benign image processing operations to become significant attack vectors. Organizations should prioritize updating graphics drivers and implementing additional browser security measures to mitigate this risk. The vulnerability underscores the need for robust input validation in all system components, particularly those handling multimedia content, as the consequences of inadequate validation can be severe system-wide failures.
