An arbitrary code execution vulnerability exists in the rendering functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242. When drawing the contents of a page using colors from an indexed colorspace, the application can miscalculate the size of a buffer when allocating space for its colors. When using this allocated buffer, the application can write outside its bounds and cause memory corruption which can lead to code execution. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.
The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
The product does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
