critical Nessus Plugin ID 90188

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2941-1 advisory.

 Kostya Kortchinsky discovered that Quagga incorrectly handled certain route data when configured with BGP peers enabled for VPNv4. A remote attacker could use this issue to cause Quagga to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2342)

 It was discovered that Quagga incorrectly handled messages with a large LSA when used in certain configurations. A remote attacker could use this issue to cause Quagga to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-2236)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
