========================================================================== Ubuntu Security Notice USN-3573-1 February 16, 2018
quagga vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - 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:
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: quagga 1.1.1-3ubuntu0.2 quagga-bgpd 1.1.1-3ubuntu0.2
