Summary
Moderate: bind9.16 security and bug fix 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.
Security Fix(es):
- bind: processing large delegations may severely degrade resolver performance (CVE-2022-2795)
- bind: flooding with UPDATE requests may lead to DoS (CVE-2022-3094)
- bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3736)
- bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3924)
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.
