medium Nessus Plugin ID 94068

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-3102-1 advisory.

 It was discovered that Quagga incorrectly handled dumping data. A remote attacker could possibly use a large BGP packet to cause Quagga to crash, resulting in a denial of service. (CVE-2016-4049)

 It was discovered that the Quagga package incorrectly set permissions on the configuration directory. A local user could use this issue to possibly obtain sensitive information. (CVE-2016-4036)

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.
