Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : quagga vulnerability (USN-775-1)

Medium Nessus Plugin ID 38758


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that the BGP service in Quagga did not correctly handle certain AS paths containing 4-byte ASNs. An authenticated remote attacker could exploit this flaw to cause bgpd to abort, leading to a denial of service.

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


Update the affected quagga and / or quagga-doc packages.
