Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the (1) process_bin_sasl_auth, (2) process_bin_complete_sasl_auth, (3) process_bin_update, and (4) process_bin_append_prepend functions due to a large body length value in a packet. A remote attacker can trigger memory corruption and cause the service to crash.
