TITLE

Adobe Flash Player Vulnerable to access restrictions

DESCRIPTION

Adobe Flash Player before 18.0.0.375 and 19.x through 23.x before 23.0.0.162 on Windows and OS X and before 11.2.202.635 on Linux allows attackers to bypass intended access restrictions and obtain sensitive information via unspecified vectors, a different vulnerability than CVE-2016-4271 and CVE-2016-4277. Adobe Flash Player is prone to multiple unspecified security-bypass vulnerabilities. The product enables viewing of applications, content and video across screens and browsers. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Critical: flash-plugin security update Advisory ID: RHSA-2016:1865-01 Product: Red Hat Enterprise Linux Supplementary Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-1865.html Issue date: 2016-09-14 CVE Names: CVE-2016-4271 CVE-2016-4272 CVE-2016-4274 CVE-2016-4275 CVE-2016-4276 CVE-2016-4277 CVE-2016-4278 CVE-2016-4279 CVE-2016-4280 CVE-2016-4281 CVE-2016-4282 CVE-2016-4283 CVE-2016-4284 CVE-2016-4285 CVE-2016-4287 CVE-2016-6921 CVE-2016-6922 CVE-2016-6923 CVE-2016-6924 CVE-2016-6925 CVE-2016-6926 CVE-2016-6927 CVE-2016-6929 CVE-2016-6930 CVE-2016-6931 CVE-2016-6932 ===================================================================== 1. Summary: An update for flash-plugin is now available for Red Hat Enterprise Linux 5 Supplementary and Red Hat Enterprise Linux 6 Supplementary. Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop Supplementary (v. 5) - i386, x86_64 Red Hat Enterprise Linux Desktop Supplementary (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server Supplementary (v. 5) - i386, x86_64 Red Hat Enterprise Linux Server Supplementary (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Supplementary (v. 6) - i386, x86_64 3. Description: The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update upgrades Flash Player to version 11.2.202.635. These vulnerabilities, detailed in the Adobe Security Bulletin listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content.
