A specifically crafted jpeg2000 file embedded in a PDF file can lead to a heap corruption when opening a PDF document in NitroPDF 12.12.1.522. With careful memory manipulation, this can lead to arbitrary code execution. In order to trigger this vulnerability, the victim would need to open the malicious file.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
