CVE-2009-3244 in Shockwave Player
Summary
by MITRE
Heap-based buffer overflow in the SwDir.dll ActiveX control in Adobe Shockwave Player 11.5.1.601 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long PlayerVersion property value.

The vulnerability identified as CVE-2009-3244 represents a critical heap-based buffer overflow within the SwDir.dll ActiveX control component of Adobe Shockwave Player versions 11.5.1.601 and earlier. This flaw exists in the handling of the PlayerVersion property value, which is processed within the ActiveX control interface that enables rich media content delivery through web browsers. The buffer overflow occurs when the application fails to properly validate or limit the length of input data passed to the PlayerVersion parameter, creating an exploitable condition in memory management.
The technical implementation of this vulnerability stems from improper bounds checking within the SwDir.dll ActiveX control's memory allocation routines. When a maliciously crafted PlayerVersion property value exceeds the allocated buffer size, memory corruption occurs in the heap memory space, potentially allowing attackers to overwrite adjacent memory locations with controlled data. This type of vulnerability maps directly to CWE-121 Heap-based Buffer Overflow, which specifically addresses buffer overflows occurring in heap memory structures where insufficient bounds checking permits writes beyond allocated memory boundaries. The vulnerability is particularly dangerous because it can be triggered through web-based attacks, leveraging the ActiveX control's integration with internet browsers to execute malicious code within the victim's system context.
The operational impact of this vulnerability extends beyond simple denial of service conditions to potentially enable remote code execution capabilities. Attackers can leverage this flaw to execute arbitrary code with the privileges of the user running the affected Shockwave Player application, which typically runs with the same permissions as the user's browser session. The vulnerability's exploitation potential aligns with ATT&CK technique T1190 - Exploit Public-Facing Application, as it targets a widely deployed ActiveX control component that is accessible through web browsers. In practice, this means that users visiting compromised websites could be automatically exploited without their knowledge, making the attack vector particularly insidious and difficult to defend against through user awareness alone.
Organizations and security professionals should prioritize immediate remediation of this vulnerability through the deployment of Adobe's security patches, which address the buffer overflow by implementing proper input validation and bounds checking mechanisms. The recommended mitigation strategy includes disabling ActiveX controls in browser environments where possible, implementing strict content security policies, and maintaining up-to-date antivirus signatures that can detect exploitation attempts. Additionally, network-level defenses such as web application firewalls and intrusion prevention systems should be configured to monitor for suspicious ActiveX control usage patterns. The vulnerability demonstrates the importance of proper memory management practices in software development and highlights the risks associated with legacy ActiveX controls that lack modern security features, particularly in enterprise environments where older software versions may still be in use.
