=====================================================================

1. Summary:

The flash-plugin package on Red Hat Enterprise Linux 4 contains multiple
security flaws and should no longer be used. This is the 1-month
notification of Red Hat's plans to disable Adobe Flash Player 9 on Red Hat
Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical
security impact.

Red Hat Enterprise Linux AS version 4 Extras - i386

3. Description:

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash
Player web browser plug-in.

Adobe Flash Player 9 is vulnerable to critical security flaws and should no
longer be used. A remote attacker could use these flaws to execute
arbitrary code with the privileges of the user running Flash Player 9.
(CVE-2011-0558, CVE-2011-0559, CVE-2011-0560, CVE-2011-0561, CVE-2011-0571,

CVE-2011-0578, CVE-2011-0607, CVE-2011-0608)

Adobe is no longer providing security updates for Adobe Flash Player 9, and
is not providing a replacement Flash Player version compatible with Red Hat
Enterprise Linux 4.

In one month Red Hat plans to release an update for the flash-plugin
package that will prevent it from functioning. User wishing to continue
using Flash Player 9, despite the vulnerabilities, can add the flash-plugin
package to the up2date skip list. Refer to the following Red Hat
Knowledgebase article for instructions on adding a package to the up2date
skip list: https://access.redhat.com/kb/docs/DOC-1639

made to the package.
