Title: Microsoft Windows Media Center MCL Vulnerability (MS15-100)
Vendor: Microsoft
Description: Windows Media Center in Microsoft Windows Vista SP2,
Windows 7 SP1, Windows 8, and Windows 8.1 allows user-assisted remote
attackers to execute arbitrary code via a crafted Media Center link
(mcl) file, aka “Windows Media Center RCE Vulnerability.”
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2015-1486
Title: Symantec Endpoint Protection Manager Authentication Bypass
Vendor: Symantec

Escalation Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6,

JavaScript code with chrome privileges via certain content navigation
that leverages the reachability of a privileged window with an
unintended persistence of access to restricted internal methods.
