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...

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: bind: SIG(0) can be used to exhaust CPU resources

A flaw was found in the bind9 package, where if a DNS server hosts a zone containing a "KEY" resource record or a DNS resolver utilizes the DNSSEC validate feature to validate a "KEY" resource record, a malicious client could exhaust the CPU resourced from the resolver by sending a stream of SIG0...

bind: bind9: BIND's database will be slow if a very large number of RRs exist at the same nam

A flaw was found in the bind9 package, where a hostname with significant resource records may slow down bind's resolver cache and authoritative zone databases while these records are being added or updated. In addition, client queries for the related hostname may cause the same issue. This...

bind: bind9: Assertion failure when serving both stale cache data and authoritative zone content

A flaw was found in the bind9 package, where a client query triggers stale data and also requires local lookups may trigger a assertion failure. This issue results in a denial of service of the bind server...
