The default configuration of Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, does not enable the Enhanced Security feature, which has unspecified impact and attack vectors, related to a "script injection vulnerability," as demonstrated by Acrobat Forms Data Format (FDF) behavior that allows cross-site scripting (XSS) by user-assisted remote attackers.

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.

The 3D implementation in Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, might allow attackers to execute arbitrary code via unspecified vectors, related to a "DLL-loading vulnerability."

The U3D implementation in Adobe Reader and Acrobat 9.x before 9.3, 8.x before 8.2 on Windows and Mac OS X, and 7.x before 7.1.4 allows remote attackers to execute arbitrary code via malformed U3D data in a PDF document, related to a CLODProgressiveMeshDeclaration "array boundary issue," a different vulnerability than CVE-2009-2994.

Use-after-free vulnerability in the Doc.media.newPlayer method in Multimedia.api 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 crafted PDF file using ZLib compressed streams, as exploited in the wild in December 2009.
