Ubuntu 6.06 LTS / 8.04 LTS / 8.10 : quagga regression (USN-775-2)
High Nessus Plugin ID 39362
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-775-1 fixed vulnerabilities in Quagga. The preventative fixes introduced in Quagga prior to Ubuntu 9.04 could result in BGP service failures. This update fixes the problem.
We apologize for the inconvenience.
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.
SolutionUpdate the affected quagga and / or quagga-doc packages.
