Debian DSA-4115-1 : quagga - security update

High Nessus Plugin ID 106854

Synopsis

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

Description

Several vulnerabilities have been discovered in Quagga, a routing daemon. The Common Vulnerabilities and Exposures project identifies the following issues :

- CVE-2018-5378 It was discovered that the Quagga BGP daemon, bgpd, does not properly bounds check data sent with a NOTIFY to a peer, if an attribute length is invalid. A configured BGP peer can take advantage of this bug to read memory from the bgpd process or cause a denial of service (daemon crash).

- CVE-2018-5379 It was discovered that the Quagga BGP daemon, bgpd, can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes, resulting in a denial of service (bgpd daemon crash).

- CVE-2018-5380 It was discovered that the Quagga BGP daemon, bgpd, does not properly handle internal BGP code-to-string conversion tables.

- CVE-2018-5381 It was discovered that the Quagga BGP daemon, bgpd, can enter an infinite loop if sent an invalid OPEN message by a configured peer. A configured peer can take advantage of this flaw to cause a denial of service (bgpd daemon not responding to any other events; BGP sessions will drop and not be reestablished;
unresponsive CLI interface).
