Cisco Cisco IOS Software Release 12.2(33)XNE

Cisco is committed to delivering secure products. We test our products internally before we release them, 
and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability 
in a Cisco product, contact PSIRT:

For emergencies only —

An emergency is either a condition in which a system is under active attack or a condition for which 
a severe and urgent security vulnerability should be reported. All other conditions are considered 
nonemergencies.

For nonemergencies —

In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302

1 408 525-6532

We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to 
encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been 
encrypted with PGP versions 2.x through 9.x. 

Never use a revoked encryption key or an expired encryption key. The correct public key to use in your 
correspondence with PSIRT is the one linked in the Contact Summary section of the Security 
Vulnerability Policy page at this URL:

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT to find other means of encrypting the data before sending 
any sensitive material.

Modifications to or updates about Cisco products are announced in Cisco Product Alerts and Cisco Field 
Notices. You can receive these announcements by using the Product Alert Tool on Cisco.com. This tool 
enables you to create a profile and choose those products for which you want to receive information.

To access the Product Alert Tool, you must be a registered Cisco.com user. Registered users can access 
the tool at this URL:
