Debian Security Advisory
DLA-601-1 quagga -- LTS security update
- Date Reported:
- 27 Aug 2016
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 835223, Bug 822787.
In Mitre's CVE dictionary: CVE-2016-4036, CVE-2016-4049.
- More information:
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.
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.
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.
