Description
A flaw was found in BIND due to a reachable assertion triggered if a TLS connection to a configured HTTP TLS listener with a defined endpoint is destroyed too early. This flaw allows a remote attacker to trigger a denial of service condition on the targeted system.
Statement
This flaw only affects BIND 9.18.0 -> 9.18.2 and BIND 9.19.0, whereas Red Hat ships BIND-9.16 and lower versions. Therefore, versions of BIND shipped with Red Hat Products are not affected by this flaw.
For RHEL-9, DHCP uses BIND 9 libraries (bind-9.11.x) for some services. Hence, DHCP shipped with RHEL-9 is also not affected.
