Description
The issue concerns multiple vulnerabilities in the Quagga package, which can lead to disruption of confidentiality, integrity, and availability of protected information. These vulnerabilities can be exploited remotely, potentially causing a denial of service (daemon crash) via a Link State Update packet. The estimated number of potentially affected devices worldwide is not specified.
Recommendations
For Quagga versions prior to 0.99.20.1, update to version 0.99.20.1 or later to resolve the issue.
