Foxit Reader V3.0 Build 1817 has fixed two security vulnerabilities and becomes more stable and safe. The fixed vulnerabilities are: a problem related to negative stream offset (in malicious JPEG2000 stream) which caused reading data from out-of-bound address, and a problem related to error handling when decoding JPEG2000 header, an uncaught fatal error resulted a subsequent invalid address access.
