Description

Kostya Kortchinsky discovered that Quagga incorrectly handled certain route data when configured with BGP peers enabled for VPNv4. A remote attacker could use this issue to cause Quagga to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-2342)

It was discovered that Quagga incorrectly handled messages with a large LSA when used in certain configurations. A remote attacker could use this issue to cause Quagga to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-2236).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
