Debian DLA-1286-1 : quagga security update

High Nessus Plugin ID 106873

Synopsis

The remote Debian host is missing a security 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).

For Debian 7 'Wheezy', these problems have been fixed in version 0.99.22.4-1+wheezy3+deb7u3.

We recommend that you upgrade your quagga packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected quagga, quagga-dbg, and quagga-doc packages.
