CVE-2004-0631: Buffer overflow in the uudecoding feature for Adobe Acrobat Reader 5.0.5 and 5.0.6 for Unix and Linux, and...

Security readout for executives and security teams

This is an old Adobe Acrobat Reader flaw affecting Unix and Linux Reader 5.0.5 and 5.0.6, with possible impact on earlier 5.x builds before 5.0.9. A maliciously named PDF handled through uudecode could overflow memory and allow code execution. Business risk is mainly from legacy systems still running unsupported Reader 5.x. Exposure is likely limited to Unix or Linux hosts with Adobe Acrobat Reader 5.0.5, 5.0.6, or possibly pre-5.0.9 5.x versions installed and used to process received PDF files. Treat this as a legacy cleanup issue with high impact if exposed. It should not outrank current actively exploited vulnerabilities unless Acrobat Reader 5.x is found in production or on sensitive workstations. Mitigation focus: Inventory Unix and Linux systems for Acrobat Reader 5.x installations.; Prioritize removal or replacement of unsupported Acrobat Reader 5.x.; Check Adobe, Red Hat, and Gentoo advisories for vendor-specific update guidance..
