RHSA-2008:0221 - Security Advisory

Topic

An updated Adobe Flash Player package that fixes several security issues is
now available for Red Hat Enterprise Linux 3 Extras, Red Hat Enterprise
Linux 4 Extras, and Red Hat Enterprise Linux 5 Supplementary.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

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

Several input validation flaws were found in the way Flash Player displayed
certain content. These may have made it possible to execute arbitrary code
on a victim's machine, if the victim opened a malicious Adobe Flash file.
(CVE-2007-0071, CVE-2007-6019)

A flaw was found in the way Flash Player established TCP sessions to remote
hosts. A remote attacker could, consequently, use Flash Player to conduct a
DNS rebinding attack. (CVE-2007-5275, CVE-2008-1655)

A flaw was found in the way Flash Player restricted the interpretation and
usage of cross-domain policy files. A remote attacker could use Flash
Player to conduct cross-domain and cross-site scripting attacks.
(CVE-2007-6243, CVE-2008-1654)

A flaw was found in the way Flash Player interacted with web browsers. An
attacker could use malicious content presented by Flash Player to conduct a
cross-site scripting attack. (CVE-2007-6637)

All users of Adobe Flash Player should upgrade to this updated package,
which contains Flash Player version 9.0.124.0 and resolves these issues.
