Summary
Important: bind and dhcp security update
Details

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. The dhcp packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.

Security Fix(es):

  • bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)
  • bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)
  • bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)

Bug Fix:

  • dhcp rebuilt after API change of bind-export-libs

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
