An issue has been found in PDF2JSON 0.69. The HtmlString class in ImgOutputDev.cc has Mismatched Memory Management Routines (malloc versus operator delete).
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
