In Foxit Reader before 9.1 and Foxit PhantomPDF before 9.1, a flaw exists within the parsing of the BITMAPINFOHEADER record in BMP files. The issue results from the lack of proper validation of the biSize member, which can result in a heap based buffer overflow. An attacker can leverage this to execute code in the context of the current process.
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.
