*** A few updates on "The Moon" worm, (Tue, Mar 25th) ***
---------------------------------------------
It has been over a month since we saw the "Moon" worm first exploiting various Linksys routers. I think it is time for a quick update to summarize some of the things we learned since then:  Much of what we found so far comes thanks to the malware analysis done by Bernado Rodriges. Bernado used QEMU to run the code in a virtual environment. QEMU is as far as I know the only widely available virtualization technique that can simulate a MIPS CPU while running on an x86 host.

*** Cisco IOS Software SSL VPN Denial of Service Vulnerability ***
---------------------------------------------
A vulnerability in the Secure Sockets Layer (SSL) VPN subsystem of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.
The vulnerability is due to a failure to process certain types of HTTP requests. To exploit the vulnerability, an attacker could submit crafted requests designed to consume memory to an affected device. An exploit could allow the attacker to consume and fragment memory on the affected device. This may cause reduced performance, a failure of certain processes, or a restart of the affected device.

*** Cisco IOS Software Session Initiation Protocol Denial of Service Vulnerability ***
---------------------------------------------
A vulnerability in the Session Initiation Protocol (SIP) implementation in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device. To exploit this vulnerability, affected devices must be configured to process SIP messages. Limited Cisco IOS Software and Cisco IOS XE Software releases are affected.

*** Cisco IOS Software Crafted IPv6 Packet Denial of Service Vulnerability ***
---------------------------------------------
A vulnerability in the implementation of the IP version 6 (IPv6) protocol stack in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause I/O memory depletion on an affected device that has IPv6 enabled. The vulnerability is triggered when an affected device processes a malformed IPv6 packet.

*** Cisco IOS Software Network Address Translation Vulnerabilities ***
---------------------------------------------
The Cisco IOS Software implementation of the Network Address Translation (NAT) feature contains two vulnerabilities when translating IP packets that could allow an unauthenticated, remote attacker to cause a denial of service condition.
---------------------------------------------
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140326-nat




*** Cisco IOS Software Internet Key Exchange Version 2 Denial of Service Vulnerability ***
---------------------------------------------
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of the affected device that would lead to a denial of service (DoS) condition.
The vulnerability is due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected device to be processed. An exploit could allow the attacker to cause a reload of the affected device that would lead to a DoS condition.

*** Web Browser Security Revisited (Part 5) ***
---------------------------------------------
In Part 1 of this series, we discussed the importance of web browser security and some security-related issues that are common to all or many of the popular browsers today. In Part 2, we talked about some specific security mechanisms that are built into Internet Explorer and how they're implemented. In Part 3, we looked at how to configure IE for best security. In Part 4, we examined how to do the same with Google Chrome. This time, we'll look at ... Chrome for Business.
