Rule Category

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.

CVE-2017-14103
The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.
