Detail
A vulnerability in the T1/E1 driver queue implementation of Cisco IOS Software could allow an unauthenticated, remote attacker to cause an interface wedge condition, which could lead to loss of connectivity, loss of routing protocol adjacency, and could result in a denial of service (DoS) scenario. The vulnerability is due to incorrect implementation of the T1/E1 driver queue. An attacker could exploit this vulnerability by sending bursty traffic through the affected interface driver. Repeated exploitation could cause a DoS condition. Workarounds to mitigate this vulnerability are available. Cisco has released free software updates that address this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130925-wedge Note: The September 25, 2013, Cisco IOS Software Security Advisory bundled publication includes eight Cisco Security Advisories. All advisories address vulnerabilities in Cisco IOS Software. Each Cisco IOS Software Security Advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all Cisco IOS Software vulnerabilities in the September 2013 bundled publication.
