HTTP: Nitro Pro PDF ICCBased ColorSpace Stroke Color Heap-based Buffer Overflow
This signature detects attempts to exploit a known vulnerability against Nitro Pro PDF. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the user.
Extended Description
An exploitable code execution vulnerability exists in the rendering functionality of Nitro Pro 13.13.2.242 and 13.16.2.300. When drawing the contents of a page and selecting the stroke color from an 'ICCBased' colorspace, the application will read a length from the file and use it as a loop sentinel when writing data into the member of an object. Due to the object member being a buffer of a static size allocated on the heap, this can result in a heap-based buffer overflow. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.
