[slackware-security]  dhcp (SSA:2022-278-01)

New dhcp packages are available for Slackware 14.0, 14.1, 14.2, 15.0,
and -current to fix security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/dhcp-4.4.3_P1-i586-1_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.
  For more information, see:
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2928
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2929
