| Vetor | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Quagga versions prior to 0.99.20.1
Quagga versions prior to 0.99.22.4
Description
The issue is related to a buffer overflow in the ospf ls upd list lsa function in ospf packet.c in the OSPFv2 implementation in ospfd. This can be exploited by remote attackers via a Link State Update packet that is smaller than the length specified in its header, leading to a denial of service. Multiple vulnerabilities in the Quagga package can also lead to disruption of confidentiality, integrity, and availability of protected information, and can be exploited remotely.
Recommendations
For Quagga versions prior to 0.99.20.1, update to version 0.99.20.1 or later.
For Quagga versions prior to 0.99.22.4, update to version 0.99.22.4 or later.
As a temporary workaround, consider restricting access to the OSPFv2 implementation to minimize the risk of exploitation.
