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-2013-3918
Title: Microsoft ActiveX Controls “InformationCardSigninHelper Class”
Out-of-Bounds Memory Access Vulnerability
Vendor: Microsoft
Description: A remote code execution vulnerability exists in the
InformationCardSigninHelper Class ActiveX control.
Specifically the issue occurs in the way “InformationCardSigninHelper
Class” ActiveX control (icardie.dll) is loaded into Internet Explorer
and causes system state corruption.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-3906
Title: Microsoft Graphics Component Could Allow Remote Code Execution
Vendor: Microsoft
Description: Remote exploitation of a memory corruption vulnerability
in multiple Microsoft products could allow attackers to execute
arbitrary code on the targeted host. The issue occurs with how the TIFF
codec in Microsoft’s graphics component handles crafted TIFF files.
Processing crafted TIFF files can corrupt system memory and create an
exploitable condition.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2012-1823
Title: PHP Group PHP CGI Query String Parameter Processing Remote Code
Execution
Vendor: PHP
Description: sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before
5.4.2, when configured as a CGI script (aka php-cgi), does not properly
handle query strings that lack an = (equals sign) character, which
allows remote attackers to execute arbitrary code by placing
command-line options in the query string, related to lack of skipping a
certain php_getopt for the ‘d’ case.
