Ubuntu 14.04 LTS / 16.04 LTS : Quagga vulnerabilities (USN-3471-1)

high Nessus Plugin ID 104323

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3471-1 advisory.

 Andreas Jaggi discovered that Quagga incorrectly handled certain BGP UPDATE messages. A remote attacker could possibly use this issue to cause Quagga to crash, resulting in a denial of service. (CVE-2017-16227)

 Quentin Young discovered that Quagga incorrectly handled memory in the telnet vty CLI. An attacker able to connect to the telnet interface could possibly use this issue to cause Quagga to consume memory, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-5495)

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

Update the affected quagga package.
