"It was discovered that there was stack overrun in IPv6 RA receive code
in quagga, a BGP/OSPF/RIP routing daemon.

The buffer size specified when receiving mixed up two constants that
have different values.

For Debian 7 'Wheezy', this issue has been fixed in quagga version
0.99.22.4-1+wheezy3+deb7u1.

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."
