CVE-2011-3323

Name of the Vulnerable Software and Affected Versions Quagga versions prior to 0.99.19 Quagga versions 0.99.15 and earlier

Description The issue affects the Quagga package, allowing remote attackers to cause a denial of service via a Link State Update message with an invalid IPv6 prefix length. This can lead to disruption of confidentiality, integrity, and availability of protected information. The exploitation can be carried out remotely.

Recommendations For Quagga versions prior to 0.99.19, update to version 0.99.19 or later to resolve the issue. For Quagga versions 0.99.15 and earlier, update to a version later than 0.99.15 to mitigate the risk. As a temporary workaround, consider restricting access to the ospf6d implementation until a patch is available.
