bind: bind9: DNS-over-HTTPS implementation suffers from multiple issues under heavy query load

A flaw was found in BIND 9. By flooding a target resolver with HTTP/2 traffic and exploiting this flaw, an attacker could overwhelm the server, causing high CPU and/or memory usage and preventing other clients from establishing DoH connections. This issue could significantly impair the resolver's...

ISC BIND 9 Vulnerable to Denial-of-Service (DoS) via Memory Leaks in EdDSA DNSSEC Verification (CVE-2022-38178)

BIND 9 is vulnerable to a denial-of-service DoS issue due to the presence of a memory leak flaw in the DNSSEC verification code for the EdDSA algorithm that can occur when there is a signature length mismatch. An attacker could spoof the target resolver with responses that have malformed EdDSA...

Astra Linux – Vulnerability in bind9

It is possible to create a zone such that certain queries to it will generate responses containing numerous records in the Additional section. An attacker sending multiple such queries can cause either the authoritative server or an independent resolver to use excessive resources to process the...

Astra Linux – Vulnerability in bind9

Clients that use DNS-over-HTTPS DoH can exhaust the CPU and/or memory of a DNS resolver by flooding it with crafted valid or invalid HTTP/2 traffic. This issue affects BIND 9 versions 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, and 9.18.11-S1 through 9.18.32-S1...

Astra Linux – Vulnerability in bind9

Client queries that trigger the delivery of stale data and also require lookups in local authoritative zone data may result in assertion failures. This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through 9.11.37-S1, 9.16.13-S1...

Astra Linux – Vulnerability in bind9

Resolver caches and authoritative zone databases that hold a significant number of Resource Records for the same hostname of any RTYPE may experience degraded performance as content is added or updated, as well as when handling client queries for this name. This issue affects BIND 9 versions 9.11...

DEBIAN-CVE-2024-12705

Clients using DNS-over-HTTPS DoH can exhaust a DNS resolver's CPU and/or memory by flooding it with crafted valid or invalid HTTP/2 traffic. This issue affects BIND 9 versions 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, and 9.18.11-S1 through 9.18.32-S1...

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: 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: 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...
