Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Quagga reports :

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.

The Quagga BGP daemon, bgpd, can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes.

The Quagga BGP daemon, bgpd, can overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value, based on input.

The Quagga BGP daemon, bgpd, can enter an infinite loop if sent an invalid OPEN message by a configured peer.

Solution

Update the affected package.
