Multiple vulnerabilities have been reported in Adobe Reader/Acrobat, which can be exploited by malicious people to compromise a user's system.

1) The application bundles a vulnerable version of Flash Player (authplay.dll).

For more information:
SA40026

NOTE: One of the vulnerabilities is currently being actively exploited.

2) An uninitialised memory error in AcroForm.api when processing JPEG image data can be exploited to bypass a recent fix and dereference out-of-bounds memory when a specially crafted PDF file is opened.

3) An array-indexing error in AcroForm.api when parsing GIF image data can be exploited to bypass a size check implemented by a recent fix and cause a heap-based buffer overflow when a specially crafted PDF file is opened.

4) An unspecified error can be exploited to corrupt memory.

5) An error when parsing a CLOD Progressive Mesh Continuation Resolution Update can be exploited to corrupt memory.

6) An unspecified error can be exploited to corrupt memory on *NIX systems.

7) An unspecified error can be exploited to corrupt memory.

8) A use-after-free error may result in a deleted heap object being dereferenced.

9) An unspecified error can be exploited to corrupt memory.

10) An unspecified error can be exploited to corrupt memory.

11) An unspecified error can be exploited to corrupt memory.

Successful exploitation of the vulnerabilities may allow execution of arbitrary code.

The vulnerabilities are reported in:
* Adobe Reader 9.3.2 (and earlier versions) for Windows, Macintosh and UNIX
* Adobe Acrobat 9.3.2 (and earlier versions) for Windows and Macintosh
* Adobe Reader 8.2.2 (and earlier versions) for Windows and Macintosh
* Adobe Acrobat 8.2.2 (and earlier versions) for Windows and Macintosh

NOTE: It has also been reported that content in a certain text field in the file launching warning dialog can be manipulated in a manner that may aid in social-engineering attacks. An error in CoolType.dll was also reported, which may cause an out-of-bounds read access violation and crash the application.
