Summary

A vulnerability in certain implementations of the TLSv1 protocol could allow 
an unauthenticated, remote attacker to access sensitive information.

The vulnerability is due to improper block cipher padding implemented in TLSv1
when using Cipher Block Chaining (CBC) mode. An attacker could exploit the 
vulnerability to perform an "oracle padding" side channel attack on the 
cryptographic message. A successful exploit could allow the attacker to access
sensitive information.

Consult the bug release note for additional information about affected 
products and configurations.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco 
Security Notices to inform customers of low- to mid-level severity security 
issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for 
these issues should contact their normal support channels. Free software 
updates will not be provided for issues that are disclosed through a Cisco 
Security Notice.

For additional information about Cisco PSIRT publications, see the Cisco 
Security Vulnerability Policy at

Customers Using Third-Party Support Organizations

Customers may have Cisco products that are provided or maintained through 
prior or existing agreements with third-party support organizations, such as 
Cisco Partners, authorized resellers, or service providers. For these 
products, customers should consult their service providers or support 
organizations to ensure that any applied workaround or fix is the most 
appropriate in the intended network before it is deployed.
