Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the UDP implementation. An unauthenticated attacker can use maliciously-crafted packets against a UDP-based vulnerable implementation of application protocols (e.g., DNS, NTP, TFTP) that can lead to Denial-of-Service (DOS) and/or abuse of resources.


Remediation

This vulnerability is considered as patched since there is a way to protect your systems against this time of attack.

Network providers should deploy available anti-spoofing techniques (BCP38) such as Unicast Reverse Path Forwarding (uRPF) to prevent IP spoofing in protecting their internet-facing resources against spoofing and abuse.
