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.
