Summary: Updated acroread packages that fix various security issues are now available for Red Hat Enterprise Linux 3 Extras, 4 Extras, and 5 Supplementary. This update has been rated as having critical security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 Extras - i386, x86_64 Red Hat Desktop version 3 Extras - i386, x86_64 Red Hat Enterprise Linux ES version 3 Extras - i386, x86_64 Red Hat Enterprise Linux WS version 3 Extras - i386, x86_64 Red Hat Enterprise Linux AS version 4 Extras - i386, x86_64 Red Hat Desktop version 4 Extras - i386, x86_64 Red Hat Enterprise Linux ES version 4 Extras - i386, x86_64 Red Hat Enterprise Linux WS version 4 Extras - i386, x86_64 RHEL Desktop Supplementary (v. 5 client) - i386, x86_64 RHEL Supplementary (v. 5 server) - i386, x86_64 3. Description: 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network.
