OVERVIEW:

       Two security vulnerabilities have been corrected in Foxit Reader 3.0 
       and JPEG/JBIG2 Decoder add-on version 2.0.2009.303 .


IMPACT:

       The vendor provides the following details:

       "Fixed a problem related to negative stream offset (in malicious 
       JPEG2000 stream) which caused reading data from an out-of-bound 
       address. We have added guard codes to solve this issue.

       Fixed a problem related to error handling when decoding JPEG2000 
       header, an uncaught fatal error resulted a subsequent invalid 
       address access. We added error handling code to terminate the 
       decoding process." [1]

       
MITIGATION:

       The vendor recommends downloading the latest Foxit Reader 3.0. [1]
       For the JPEG/JBIG2 Decoder add-on, update to the latest version 2.0
       build by selecting "Check for updates now" in the Reader help menu.
