Summary

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.
