RedHat: RHSA-2022-2092:01 Moderate: bind security, bug fix,
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.
The following packages have been upgraded to a later upstream version: bind
(9.11.36). (BZ#2013993)
Security Fix(es):
* bind: Lame cache can be abused to severely degrade resolver performance
(CVE-2021-25219)
