Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper resource management when processing UDP packets. A remote attacker can send a large amount of specially crafted UDP packets, trigger resource exhaustion and perform a denial of service (DoS) attack.
