Summary

A vulnerability in the SSL logging daemon of Cisco Application Control Engine (ACE) could allow an unauthenticated, remote attacker to cause a denial of service condition on the affected device.

The vulnerability occurs because the Cisco ACE fails to rotate logs from SSL sessions, exhausting the hard drive of free space. An attacker could exploit this vulnerability by sending excessive amounts of SSL connections to the affected device. An exploit could allow the attacker to exhaust remaining free space on the hard drive, causing operations such as configuration and writing configurations on the disk to fail. Additional errors can be observed on the Cisco ACE console.

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 http://www.cisco.com/web/about/security/psirt/security_vulnerability_policy.html

Customers Using Third-Party Support Organizations

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.
