Detail
Cisco IOS Software contains a vulnerability in the Border Gateway Protocol (BGP) routing protocol feature. The vulnerability can be triggered when the router receives a malformed attribute from a peer on an existing BGP session. Successful exploitation of this vulnerability can cause all BGP sessions to reset. Repeated exploitation may result in an inability to route packets to BGP neighbors during reconvergence times. Cisco has released free software updates that address this vulnerability. There are no workarounds for this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120926-bgp Note: The September 26, 2012, Cisco IOS Software Security Advisory bundled publication includes 9 Cisco Security Advisories. Eight of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses a vulnerability in Cisco Unified Communications Manager. 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 2012 bundled publication.
