    Multiple vulnerabilities have been reported in Adobe Reader:
    Alin Rad Pop of Secunia Research reported a heap-based buffer
    overflow in the JBIG2 filter (CVE-2009-0198).
    Mark Dowd of the IBM Internet Security Systems X-Force and
    Nicolas Joly of VUPEN Security reported multiple heap-based buffer
    overflows in the JBIG2 filter (CVE-2009-0509, CVE-2009-0510,
    CVE-2009-0511, CVE-2009-0512, CVE-2009-0888, CVE-2009-0889)
    Arr1val reported that multiple methods in the JavaScript API
    might lead to memory corruption when called with crafted arguments
    (CVE-2009-1492, CVE-2009-1493).
    An anonymous researcher reported a stack-based buffer overflow related
    to U3D model files with a crafted extension block (CVE-2009-1855).
    Jun Mao and Ryan Smith of iDefense Labs reported an integer overflow
    related to the FlateDecode filter, which triggers a heap-based buffer
    overflow (CVE-2009-1856).
    Haifei Li of Fortinet's FortiGuard Global Security Research Team
    reported a memory corruption vulnerability related to TrueType fonts
    (CVE-2009-1857).
    The Apple Product Security Team reported a memory corruption
    vulnerability in the JBIG2 filter (CVE-2009-1858).
    Matthew Watchinski of Sourcefire VRT reported an unspecified memory
    corruption (CVE-2009-1859).
    Will Dormann of CERT reported multiple heap-based buffer overflows when
    processing JPX (aka JPEG2000) stream that trigger heap memory
    corruption (CVE-2009-1861).
    Multiple unspecified vulnerabilities have been discovered
    (CVE-2009-2028).
  
Impact :

    A remote attacker could entice a user to open a specially crafted
    document, possibly resulting in the execution of arbitrary code with
    the privileges of the user running the application.
  
Workaround :

    There is no known workaround at this time."
