Ubuntu Security Notice USN-3102-1

quagga vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  quagga                          0.99.24.1-2ubuntu1.1

Ubuntu 14.04 LTS:
  quagga                          0.99.22.4-3ubuntu1.2

Ubuntu 12.04 LTS:
  quagga                          0.99.20.1-0ubuntu0.12.04.5

After a standard system update you need to restart Quagga to make all the
necessary changes.
