Summary

Adobe Acrobat Reader allows users to view and print documents in Portable Document Format (PDF).
An input validation flaw was discovered in a JavaScript engine used by Acrobat Reader. A malicious PDF file could cause Acrobat Reader to crash or, potentially, execute arbitrary code as the user running Acrobat Reader. (CVE-2008-2641)
An insecure temporary file usage issue was discovered in the Acrobat Reader "acroread" startup script. A local attacker could potentially overwrite arbitrary files that were writable by the user running Acrobat Reader, if the victim ran "acroread" with certain command line arguments. (CVE-2008-0883)
All acroread users are advised to upgrade to these updated packages, that contain Acrobat Reader version 8.1.2 Security Update 1, and are not vulnerable to these issues.
