  script_tag(name:"insight", value:"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).

[link moved to references]

CVE-2018-5380

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

[link moved to references]

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 the oldstable distribution (jessie), these problems have been fixed in version 0.99.23.1-1+deb8u5.

For the stable distribution (stretch), these problems have been fixed in version 1.1.1-3+deb9u2.

We recommend that you upgrade your quagga packages.
