Description Adam Mariš 2018-02-07 08:41:14 EST 
The Quagga BGP daemon, bgpd, does not properly bounds check the data sent with a NOTIFY to a peer, if an attribute length is invalid. Arbitrary data from the bgpd process may be sent over the network to a peer and/or it may crash.

Affected versions: 1.1.0, 1.1.1, 1.2.0, 1.2.1, 1.2.2
