Description

An updated Adobe Flash Player package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6 Supplementary.

Red Hat Product Security has rated this update as having Critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

This update fixes one vulnerability in Adobe Flash Player. This vulnerability is detailed in the Adobe Security Bulletin APSB14-26, listed in the References section.

A flaw was found in the way flash-plugin displayed certain SWF content. An attacker could use this flaw to create a specially crafted SWF file that would cause flash-plugin to crash or, potentially, execute arbitrary code when the victim loaded a page containing the malicious SWF content. (CVE-2014-8439)

All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 11.2.202.424.
