Critical: acroread security update

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.

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.
