USN-512-1: Quagga vulnerability

15 September 2007

Quagga vulnerability

Releases

Packages

Details

It was discovered that Quagga did not correctly verify OPEN messages or
COMMUNITY attributes sent from configured peers. Malicious authenticated
remote peers could send a specially crafted message which would cause
bgpd to abort, leading to a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
