Heap-based buffer overflow in the JBIG2 filter in Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 allows remote attackers to execute arbitrary code via a crafted file that triggers memory corruption.

Security readout for executives and security teams

This flaw lets a malicious PDF trigger memory corruption in older Adobe Reader and Acrobat versions. Successful exploitation could run attacker-controlled code with the user’s privileges. The main business risk is compromise through opening a crafted document on legacy endpoints. Exposure is mainly legacy systems still running Adobe Reader or Acrobat 7 before 7.1.3, 8 before 8.1.6, or 9 before 9.1.2. Distribution-packaged Adobe Reader should be checked against relevant vendor advisories. Prioritize remediation where legacy Adobe PDF software remains on user workstations, especially email-facing or document-processing environments. This is an old vulnerability, but the impact is high if obsolete versions persist. Mitigation focus: Upgrade Adobe Reader/Acrobat to the fixed versions or later.; Review Adobe APSB09-07 and applicable OS vendor advisories.; Remove unsupported legacy Reader/Acrobat installations where business need is absent..
