CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
quagga on Debian Linux

For the oldstable distribution (jessie), these problems have been fixed in version For the stable distribution (stretch), these problems have been fixed in version 1.1.1-3+deb9u2. We recommend that you upgrade your quagga Linux Distribution Packages. For the detailed security status of quagga please refer to its security tracker page linked in the references.

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).

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
