Red Hat Security Advisory
Synopsis: Critical: flash-plugin security update
Advisory ID: RHSA-2009:0332-01
Product: Red Hat Enterprise Linux Extras
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0332.html
Issue date: 2009-02-25
CVE Names: CVE-2009-0519 CVE-2009-0520 CVE-2009-0521
=====================================================================
1. Summary:
An updated Adobe Flash Player package that fixes several security issues is
now available for Red Hat Enterprise Linux 5 Supplementary.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
RHEL Desktop Supplementary (v. 5 client) - i386, x86_64
RHEL Supplementary (v. 5 server) - i386, x86_64
3. Description:
The flash-plugin package contains a Firefox-compatible Adobe Flash Player
Web browser plug-in.
Multiple input validation flaws were found in the way Flash Player
displayed certain SWF (Shockwave Flash) content. An attacker could use
these flaws to create a specially-crafted SWF file that could cause
flash-plugin to crash, or, possibly, execute arbitrary code when the victim
loaded a page containing the specially-crafted SWF content. (CVE-2009-0520,
CVE-2009-0519)
It was discovered that Adobe Flash Player had an insecure RPATH (runtime
library search path) set in the ELF (Executable and Linking Format) header.
A local user with write access to the directory pointed to by RPATH could
use this flaw to execute arbitrary code with the privileges of the user
running Adobe Flash Player. (CVE-2009-0521)
All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 10.0.22.87.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

the Red Hat Network to apply this update are available at
