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).


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.


There is no known workaround at this time.


All Adobe Reader users should upgrade to the latest version:
