This update fixes multiple vulnerabilities in Adobe Flash Player. These
vulnerabilities are detailed in the Adobe Security Bulletin APSB15-02, and
APSB15-03, 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-2015-0310, CVE-2015-0311, CVE-2015-0312)
All users of Adobe Flash Player should install this updated package, which
