Core Security Technologies Advisory - Corel Paint Shop Pro Photo X2 is prone to a heap-based buffer overflow when processing malformed FPX files, because it trusts user-controlled data located inside a FPX file and uses it as a loop counter when copying data from a FPX file into a fixed-size buffer located in the heap. This vulnerability can be exploited to overwrite adjacent heap chunks metadata, and possibly to gain arbitrary code execution.
