quagga vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Quagga.
Software Description: - quagga: BGP/OSPF/RIP routing daemon
Details:
Andreas Jaggi discovered that Quagga incorrectly handled certain BGP UPDATE messages. A remote attacker could possibly use this issue to cause Quagga to crash, resulting in a denial of service. (CVE-2017-16227)
Quentin Young discovered that Quagga incorrectly handled memory in the telnet vty CLI. An attacker able to connect to the telnet interface could possibly use this issue to cause Quagga to consume memory, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-5495)
