bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution
A flaw was found in the bind package. This issue may allow an attacker to query in a DNS64 enabled resolver node with a domain name triggering a server-stale data, triggering a code assertion, and resulting in a crash of named processes. This can allow a remote unauthenticated user to cause a...
bind9: Specific recursive query patterns may lead to an out-of-memory condition
A flaw was found in the named application, part of the bind9 package, which uses a cache database to speeds up DNS queries. To maintain its efficiency when running as a recursive name resolver, named performs a cache database clean up under certain conditions. This issue may allow an attacker to...
bind9: Parsing large DNS messages may cause excessive CPU load
A flaw was found in the bind package. This issue may allow a remote attacker with no specific privileges to craft a specially long DNS message leading to an excessive and uncontrolled CPU usage, the server being unavailable, and a Denial of Service...
bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator
Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. This vulnerability applies only for systems where DNSSEC validation is enabled...
Important: Red Hat Security Advisory: bind security update
An update for bind is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the...
bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources
A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...

bind9: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled
A flaw was found in the bind package which may result in a Denial of Service in named process. This is a result of a reachable assertion, leading named to prematurely terminate when both conditions are met: nxdomain-redirect for the queried domain is configured and the resolver receives a PTR...
