RedHat: RHSA-2023-2261:01 Moderate: bind
Summary
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)
