FILE-IMAGE -- Snort detected suspicious traffic targeting vulnerabilities found inside images files, regardless of delivery method, targeted software, or image type. (Examples include: jpg, png, gif, bmp). These rules search for malformed images used to exploit system. Attackers alter image attributes, often to include shell code, so they are susceptible to vulnerabilities when they are parsed and send commands instead of loading the image.

Buffer Overflow
Buffer Overflows occur when a memory location is filled past its expected boundaries. Computer attackers target systems without proper terminating conditions on buffers, which then write the additional information in other locations in memory, overwriting what is there. This could corrupt the data, making the system behave erratically or crash. The new information could include malicious executable code, which might be executed.
