quagga vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 16.04 LTS

Summary:
Several security issues were fixed in Quagga.
Software Description:

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)
