    - A use-after-free vulnerability in Multimedia.api that could lead to code execution (CVE-2009-4324).
    Note: There are reports of this issue being actively exploited in the wild; the exploit targets Adobe Reader and Acrobat 9.2 on Windows platforms.

    - An array boundary issue in U3D support that could lead to code execution (CVE-2009-3953).
    Note: This issue had been incorrectly identified as a previously fixed vulnerability (CVE-2009-2994) in the Metasploit framework.

    - A DLL-loading vulnerability in 3D that could allow arbitrary code execution (CVE-2009-3954).

    - A memory corruption vulnerability that could lead to code execution (CVE-2009-3955).

    - A script injection vulnerability by changing the Enhanced Security default (CVE-2009-3956).

    - A null-pointer dereference vulnerability that could lead to denial of service (CVE-2009-3957).

    A buffer overflow vulnerability in the Download Manager that could lead to code execution (CVE-2009-3958).

    - An integer overflow vulnerability in U3D support that could lead to code execution (CVE-2009-3959).

    Successful exploitation of this vulnerability could cause a crash and potentially allow an attacker to take control of the affected system.
    Adobe has released updates to resolve this issue. Refer to Adobe Security Bulletin APSB10-02 to obtain patch details. Also refer to Adobe Security Advisory APSA09-07 to obtain additional details on the vulnerability.

    The vendor has recommended the following mitigation techniques until a patch is applied.

    Customers using Adobe Reader or Acrobat versions 9.2 or 8.1.7 can utilize the JavaScript Blacklist Framework to prevent this vulnerability. Please refer to the Adobe TechNote for more information.

    2) Select Edit>Preferences.
    3) Select the JavaScript Category.
    4) Uncheck the "Enable Acrobat JavaScript" option.
    5) Click OK.
