Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
