Cisco stamps patches on timestamp flaws

For more information Check out our white paper on managing Cisco network security. Learn more about troubleshooting VPNs.

The vulnerability is caused due to a TCP timestamp option error. The flaws allow a remote user to send a packet with specially crafted TCP timestamp options, ultimately causing a target TCP connection to stall until the TCP connection is reset.

The advisory said knowledge of IP address information of the source and destination of the TCP network connection is required for successful exploitation.

Only systems running VxWorks, a real-time operating system for embedded software and process control applications, are affected.

Systems running VxWorks can be upgraded to Cisco IOS to address this issue; access points running Cisco IOS are not affected.

The Cisco advisory recommends that users apply vendor-provided patches.
