From 153ac9bb204e55276263530db56bd39540d15b53 Mon Sep 17 00:00:00 2001 From: Patrick J Volkerding Date: Wed, 5 Oct 2022 18:55:36 +0000 Subject: Wed Oct 5 18:55:36 UTC 2022 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.
