Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated Adobe Flash Player package that fixes multiple security
issues 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. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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

This update fixes multiple vulnerabilities in Adobe Flash Player.
These vulnerabilities are detailed in the Adobe Security Bulletin
APSB15-09 listed in the References section.

Multiple flaws were found in the way flash-plugin displayed certain
SWF content. An attacker could use these flaws 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-2015-3077, CVE-2015-3078,
CVE-2015-3080, CVE-2015-3082, CVE-2015-3083, CVE-2015-3084,
CVE-2015-3085, CVE-2015-3086, CVE-2015-3087, CVE-2015-3088,
CVE-2015-3089, CVE-2015-3090, CVE-2015-3093)

A security bypass flaw was found in flash-plugin that could lead to
the disclosure of sensitive information. (CVE-2015-3079)

Two memory information leak flaws were found in flash-plugin that
could allow an attacker to potentially bypass ASLR (Address Space
Layout Randomization) protection, and make it easier to exploit other
flaws. (CVE-2015-3091, CVE-2015-3092)

All users of Adobe Flash Player should install this updated package,
which upgrades Flash Player to version 11.2.202.460.
