===========================================================================

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:
- quagga: BGP/OSPF/RIP routing daemon

Details:

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)
