Ubuntu 14.04 LTS / 16.04 LTS : Quagga vulnerabilities (USN-3573-1)

critical Nessus Plugin ID 106869

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3573-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected quagga package.
