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. 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 fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities are detailed in the Adobe Security Bulletin APSB15-11 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-2015-3100, CVE-2015-3103, CVE-2015-3104, CVE-2015-3105, CVE-2015-3106, CVE-2015-3107) Multiple security bypass flaws were found in flash-plugin that could lead to the disclosure of sensitive information. (CVE-2015-3096, CVE-2015-3098, CVE-2015-3099, CVE-2015-3102) A memory information leak flaw was 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-2015-3108) All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 11.2.202.466. 4.
