SphireOS 252.19 Release Notes

Welcome to SphireOS release 252.19!


  • We fixed an issue that could cause a buffer overflow and crash SphireOS.
  • We improved the way we capture and log radius accounting packets. This should result in better and more detailed error logs.
  • We improved the way we collect statistics on packets.
  • The transparent proxy service in SphireOS won’t crash HTTPS inspection is enabled.
  • Sphirewall won’t keep trying to send DHCP requests if the link is down. Creating a rule with empty or missing criteria won’t cause  SphireOS to crash.
  • SphireOS no longer cares about letter cases in group names when you’re creating and applying filtering rules.
  • We found and fixed a rare case where SphireOS wouldn’t process all LDAP records, resulting in users incorrectly being set as archived.
  • SphireOS won’t apply HTTPs inspection to additional subnet ranges if subnets were specified in IP/Subnet notation. SphireOS won’t crash if you update user or group configuration while HTTPS Inspection is enabled.
