    Multiple heap-based buffer overflows in Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF file with a JPX (aka JPEG2000) stream that triggers heap memory corruption.
