Overview

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to unbounded nesting of composite buffers in the SCTP message reassembly process. An attacker can exhaust system memory and cause a denial of service by sending a large number of incomplete message fragments, each creating deeper buffer chains without limit.
