A flaw was found in Erlang OTP (Open Telecom Platform) erts, specifically within the inet_drv component. An unauthenticated remote attacker can exploit a stack-based buffer overflow vulnerability by sending a specially crafted Stream Control Transmission Protocol (SCTP) ERROR chunk. This can lead to a Denial of Service (DoS) by crashing the BEAM virtual machine. Additionally, this flaw may result in limited information disclosure by leaking small portions of Erlang VM memory.
