Microsoft Internet Explorer 10 and 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Internet Explorer Memory Corruption Vulnerability," a different vulnerability than CVE-2015-1733 and CVE-2015-2389.

The version of Internet Explorer installed on the remote host is missing Cumulative Security Update 3076321. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website.

Hosts running Internet Explorer 10 or Internet Explorer 11 will not be fully protected until both security update 3065822 and security update 3075516 are applied to the system. Security update 3075516 may require manual installation depending on your patching method.

Note that the majority of the vulnerabilities addressed by Cumulative Security Update 3076321 are mitigated by the Enhanced Security Configuration (ESC) mode which is enabled by default on Windows Server 2003, 2008, 2008 R2, 2012, and 2012 R2.

A vulnerability in Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to install and execute an arbitrary executable file with privileges equivalent to the Microsoft Windows operating system SYSTEM account.

The vulnerability is due to a lack of checks in the code for the path and filename of the file that is to be installed. An attacker could exploit this vulnerability by creating a specially modified INF file. An exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to the SYSTEM account.
