RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM

This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.

ID: CVE-2015-0816
Title: Mozilla Firefox “resource:// document” Design Error Privilege
Escalation Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6,
and Thunderbird before 31.6 do not properly restrict resource: URLs,
which makes it easier for remote attackers to execute arbitrary
JavaScript code with chrome privileges by leveraging the ability to
bypass the Same Origin Policy, as demonstrated by the resource: URL
associated with PDF.js.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N)

ID: CVE-2015-0802
Title: Mozilla Firefox Privileged Window Design Error Security Bypass
Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0 relies on docshell type
information instead of page principal information for Window.webidl
access control, which might allow remote attackers to execute arbitrary
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.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N)

ID: CVE-2014-6332
Title: Microsoft Windows OLE Automation Array Memory Corruption Code

Vendor: Microsoft
Description: OleAut32.dll in OLE in Microsoft Windows Server 2003 SP2,
Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1,
Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT
Gold and 8.1 allows remote attackers to execute arbitrary code via a
crafted web site, as demonstrated by an array-redimensioning attempt
that triggers improper handling of a size value in the SafeArrayDimen
function, aka “Windows OLE Automation Array Remote Code Execution
Vulnerability.”
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2015-5122

ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through
13.0.0.296 and 14.x through 18.0.0.194 on Windows and OS X and 11.x
through 11.2.202.468 on Linux allows remote attackers to execute
arbitrary code or cause a denial of service (memory corruption) via
crafted Flash content that overrides a ValueOf function, as exploited
in the wild in July 2015.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2015-3090

Adobe AIR before 17.0.0.172, Adobe AIR SDK before 17.0.0.172, and Adobe
AIR SDK & Compiler before 17.0.0.172 allow attackers to execute
arbitrary code or cause a denial of service (memory corruption) via
unspecified vectors, a different vulnerability than CVE-2015-3078,
CVE-2015-3089, and CVE-2015-3093.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2015-3113
