A vulnerability has been discovered in Quagga allowing for a Denial of Service.
Quagga is a free routing daemon, supporting RIP, OSPF and BGP protocols.
The Quagga development team reported a vulnerability in the BGP routing deamon when processing NLRI attributes inside UPDATE messages.
A malicious peer inside a BGP area could send a specially crafted packet to a Quagga instance, possibly resulting in a crash of the Quagga daemon.
There is no known workaround at this time.
All Quagga users should upgrade to the latest version:
