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 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 188.8.131.520. 4.
