HIGH 8.8

DescriptionNVD

Stack-based buffer overflow in Adobe Reader and Adobe Acrobat 9 before 9.1, 8 before 8.1.3 , and 7 before 7.1.1 allows remote attackers to execute arbitrary code via a crafted argument to the getIcon method of a Collab object, a different vulnerability than CVE-2009-0658.

AnalysisAI

Adobe Reader and Acrobat 9.x, 8.x, and 7.x contain a stack-based buffer overflow in the getIcon method of the Collab object that allows remote attackers to execute arbitrary code via a crafted PDF argument.

Technical ContextAI

The CWE-20 vulnerability is triggered when a PDF contains JavaScript that calls Collab.getIcon() with an overly long argument, overflowing the stack buffer and allowing the attacker to control the instruction pointer for arbitrary code execution.

RemediationAI

Upgrade to patched Adobe Reader/Acrobat versions. Modern systems should use alternative PDF readers with sandboxing. Disable JavaScript execution in PDF readers where possible.
