quagga vulnerabilities

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

- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS


Several security issues were fixed in Quagga.

Software Description:
- - quagga: BGP/OSPF/RIP routing daemon


It was discovered that a double-free vulnerability existed in the
Quagga BGP daemon when processing certain forms of UPDATE message.
A remote attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2018-5379)

It was discovered that the Quagga BGP daemon did not properly bounds
check the data sent with a NOTIFY to a peer. An attacker could use this
to expose sensitive information or possibly cause a denial of service.
This issue only affected Ubuntu 17.10. (CVE-2018-5378)

It was discovered that a table overrun vulnerability existed in the
Quagga BGP daemon. An attacker in control of a configured peer could
use this to possibly expose sensitive information or possibly cause
a denial of service. (CVE-2018-5380)

It was discovered that the Quagga BGP daemon in some configurations
did not properly handle invalid OPEN messages. An attacker in control
of a configured peer could use this to cause a denial of service
(infinite loop). (CVE-2018-5381)
