The vulnerability allows a remote attacker to perform DoS attack.

The vulnerability exists due to an implementation error in DTLS 1.0/1.2, which causes the return-routability check, intended to protect application against DoS attacks, to be wrongly skipped in a specific edge case. A remote attacker can perform a denial of service (DoS) attack by consuming excessive resources on the server.
