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.
