Integer overflow in the Type 1 font decoder in the FreeType engine in Foxit Reader before 4.0.0.0619 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted font in a PDF document.

Foxit Reader 2.3 before Build 3902 and 3.0 before Build 1506, including 3.0.2009.1301, does not properly handle a JBIG2 symbol dictionary segment with zero new symbols, which allows remote attackers to execute arbitrary code via a crafted PDF file that triggers a dereference of an uninitialized memory location.

Foxit Reader before 3.2.1.0401 allows remote attackers to (1) execute arbitrary local programs via a certain "/Type /Action /S /Launch" sequence, and (2) execute arbitrary programs embedded in a PDF document via an unspecified "/Launch /Action" sequence, a related issue to CVE-2009-0836.

The Foxit JPEG2000/JBIG2 Decoder add-on before 2.0.2009.616 for Foxit Reader 3.0 before Build 1817 does not properly handle a negative value for the stream offset in a JPEG2000 (aka JPX) stream, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted PDF file that triggers an out-of-bounds read.
