Description

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

The vulnerability exists due to improper input validation. A remote authenticated attacker can send a specially crafted packet, trigger resource exhaustion and cause a denial of service condition on the target system.

Mitigation
Install updates from vendor's website.
