Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when the affected software does not call "process_new_packets" immediately after "read", so the expected termination condition "wants_read" always returns true. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
Mitigation
Install updates from vendor's website.
