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.
FILE-IMAGE Adobe Acrobat Pro EMR_STRETCHDIBITS out-of-bounds write attempt
This event is generated when an attempt to exploit a vulnerability in the EMR_STRETCHDIBITS record of an EMF file, is detected. Impact: High Details: The vulnerability is caused by the computation that writes data past the end of the intended buffer; the computation is part of the image conversion engine when processing Enhanced Metafile Format (EMF) data related to block transfer of pixels. A crafted input triggers the flawed computation where pointer arithmetic is not appropriately checked against boundary conditions, which leads to memory write operation through the pointer that points to an invalid memory location. Ease of Attack: Simple
