Important Notes

IOS IPS Important Notice
IOS IPS customers running version 12.4T, 15.0M, or 15.1M - a critical software defect has been identified which may cause your router to reload and be stuck in a boot loop if IOS IPS signature version S639 or later is installed on the device. Recovery of impacted devices is possible only via a serial console connection through the device's ROMMON mode. For customers who are using IOS IPS signatures S638 or earlier, there is no issues. Customers wishing to upgrade the IOS IPS signature version to S639 or later must first be running a fixed version of IOS on the device prior to upgrading the IPS signatures. Fixed versions of IOS include: 15.2(4)M, 15.1(3)T4, 15.2(3)T1, 15.1(4)M5, 12.4(24)T8 and later. Please refer to defect CSCtz27137 for additional details and steps to recover impacted devices. A link to download the latest Cisco IOS software for your device is provided below. If you need further assistance please contact Cisco TAC.

New Vulnerability and Exploit Protections
Microsoft Internet Explorer Remote Arbitrary Code Execution Vulnerability
Vulnerability Disclosed: 1/14/2010, CVSS Base: 9.3, Temporal: 8.4
Microsoft Internet Explorer contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the user.
The vulnerability is due to an invalid pointer reference. An unauthenticated, remote attacker could exploit this vulnerability by creating a malicious website and convincing a targeted user to visit the site. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the user.
Functional code that exploits this vulnerability on systems that run Internet Explorer 6 is publicly available.
Microsoft has confirmed this vulnerability and released software updates.
More Details: CVE-2010-0249
Microsoft Office Rich Text Format Content Processing Buffer Overflow Vulnerability Vulnerability Disclosed: 11/9/2010, CVSS Base: 9.3, Temporal: 6.9
Microsoft Office contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability is due to improper boundary restrictions when processing Office documents. An unauthenticated, remote attacker could exploit the vulnerability by convincing the user to view a malicious document. If successful, the attacker could execute arbitrary code with the privileges of the user.
A functional exploit that is a part of the Metasploit framework is publicly available.
Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
More Details: CVE-2010-3333 Applied Mitigation Bulletin: 21766 CVE-2010-3333 Applied Mitigation Bulletin: 21766 CVE-2010-3333 Applied Mitigation Bulletin: 21766

Cisco has confirmed this vulnerability in a security advisory and has released updated software.
More Details: CVE-2012-3076 Cisco PSIRT: cisco-sa-20120711-ctrs
Cisco TelePresence Immersive Endpoint Devices API Remote Command Execution Vulnerability
Vulnerability Disclosed: 7/11/2012, CVSS Base: 8.3, Temporal: 6.9
Cisco TelePresence application programming interfaces (APIs) that are hosted on Cisco TelePresence endpoint devices contain a vulnerability related to Cisco TelePresence Immersive Endpoint System that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted device.
The vulnerability is due to improper processing of malformed requests by the affected software. An unauthenticated, remote attacker on an adjacent network could exploit this vulnerability by sending malicious requests to the device. If successful, the attacker could execute arbitrary commands on the device with elevated privileges, possibly resulting in a complete compromise.
Cisco has confirmed the vulnerability in a security advisory and released software updates.
