Overview

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling when the named function processes control channel messages, it calls certain functions recursively during packet parsing. An attacker can cause named to terminate unexpectedly by sending a specially crafted packet that exhausts available stack memory. This is only exploitable if network access to the control channel's configured TCP port is available.

Mitigation: This vulnerability can be mitigated by limiting remote access to the control channel's configured TCP port to trusted IP ranges on the network level.
