patches/packages/dhcp-4.4.3_P1-x86_64-1_slack15.0.txz:  Upgraded.
  This update fixes two security issues:
  Corrected a reference count leak that occurs when the server builds
  responses to leasequery packets.
  Corrected a memory leak that occurs when unpacking a packet that has an
  FQDN option (81) that contains a label with length greater than 63 bytes.
  Thanks to VictorV of Cyber Kunlun Lab for reporting these issues.
