Several readers have written in that Cisco just released three security bulletins regarding issues in the Cisco IOS software:
Crafted TCP Packet can cause denial of service
Crafted IP Option vulnerability
IPv6 Routing Header vulnerability
We are currently performing a more detailed analysis of each of these vulnerabilities and will post updates to these issues shortly. As a form of triage we believe organizations are most likely to be affected by the 'Crafted IP Option vulnerability', which simultaneously has the highest potential impact.
If you run Cisco switches or routers in your network, we advise you to review these bulletins in detail and take mitigative action where required.
