The quagga package before 0.99.23-2.6.1 in openSUSE and SUSE Linux Enterprise Server 11 SP 1 uses weak permissions for /etc/quagga, which allows local users to obtain sensitive information by reading files in the directory.

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-3102-1 advisory.

    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)

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.

The quagga package installs world readable sensitive files in /etc/quagga, and might be subject to denial of service because of lacking packet size checks.

CVE-2016-4036

The quagga package before 0.99.23-2.6.1 uses weak permissions for /etc/quagga, which allows local users to obtain sensitive information by reading files in the directory.

CVE-2016-4049

The bgp_dump_routes_func function in bgpd/bgp_dump.c in Quagga does not perform size checks when dumping data, which might allow remote attackers to cause a denial of service (assertion failure and daemon crash) via a large BGP packet.

For Debian 7 'Wheezy', these problems have been fixed in version 0.99.22.4-1+wheezy3.

We recommend that you upgrade your quagga packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Two vulnerabilities were discovered in quagga, a BGP/OSPF/RIP routing daemon.

  - CVE-2016-4036     Tamas Nemeth discovered that sensitive configuration     files in /etc/quagga were world-readable despite     containing sensitive information.

  - CVE-2016-4049     Evgeny Uskov discovered that a bgpd instance handling     many peers could be crashed by a malicious user when     requesting a route dump.
