Debian DLA-601-1 : quagga security update

high Nessus Plugin ID 93130

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected quagga, quagga-dbg, and quagga-doc packages.
