Medium Nessus Plugin ID 94068


The remote Ubuntu host is missing a security-related patch.


It was discovered that Quagga incorrectly handled dumping data. A remote attacker could possibly use a large BGP packet to cause Quagga to crash, resulting in a denial of service. (CVE-2016-4049)

It was discovered that the Quagga package incorrectly set permissions on the configuration directory. A local user could use this issue to possibly obtain sensitive information. (CVE-2016-4036).

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.


Update the affected quagga package.
