Multiple stack-based buffer overflows in the NOS Microsystems getPlus Helper ActiveX control before 1.6.2.49 in gp.ocx in the Download Manager in Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, might allow remote attackers to execute arbitrary code via unspecified initialization parameters.

Integer overflow in the U3D implementation in Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a malformed PDF document.

Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a crafted JPC_MS_RGN marker in the Jp2c stream of a JpxDecode encoded data stream, which triggers an integer sign extension that bypasses a sanity check, leading to memory corruption.

Heap-based buffer overflow in Adobe Acrobat Reader and Acrobat Professional 7.1.0, 8.1.3, 9.0.0, and other versions allows remote attackers to execute arbitrary code via a PDF file containing a JBIG2 stream with a size inconsistency related to an unspecified table.
