Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions during the hostname sanitizing when specific configuration parameters are set: hostname-char-set remains at its default value, hostname-char-replacement is empty (default), and ddns-qualifying-suffix is not empty. An attacker can cause the process to exit unexpectedly by sending crafted option content. This is only exploitable if all three configuration parameters are set as described.
This vulnerability can be mitigated by setting "hostname-char-replacement" to any non-empty value (e.g., "x").
