Name Overflow Binary Resource File
Summary An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
Prerequisites Target software processes binary resource files. Target software contains a buffer overflow vulnerability reachable through input from a user-controllable binary resource file.
Solutions Perform appropriate bounds checking on all buffers. Design: Enforce principle of least privilege Design: Static code analysis Implementation: Execute program in less trusted process space environment, do not allow lower integrity processes to write to higher integrity processes Implementation: Keep software patched to ensure that known vulnerabilities are not available for attackers to target on host.
