Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the MSG_IO_TIMEOUT process. An attacker can cause resource exhaustion by injecting specially crafted MSG_IO_TIMEOUT messages with non-positive values, which disables connection timeouts and allows idle or stalled connections to occupy daemon slots indefinitely.
