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

 

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.
