SUSE CVE-2013-3919

resolver.c in ISC BIND 9.8.5 before 9.8.5-P1, 9.9.3 before 9.9.3-P1, and 9.6-ESV-R9 before 9.6-ESV-R9-P1, when a recursive resolver is configured, allows remote attackers to cause a denial of service assertion failure and named daemon exit via a query for a record in a malformed zone...

SUSE CVE-2015-4620

name.c in named in ISC BIND 9.7.x through 9.9.x before 9.9.7-P1 and 9.10.x before 9.10.2-P2, when configured as a recursive resolver with DNSSEC validation, allows remote attackers to cause a denial of service REQUIRE assertion failure and daemon exit by constructing crafted zone data and then...

unbound: amplification of an incoming query into a large number of queries directed to a target

A network amplification vulnerability was found in Unbound, in the way it processes delegation messages from one authoritative zone to another. This flaw allows an attacker to cause a denial of service or be part of an attack against another DNS server when Unbound is deployed as a recursive...

According to the versions of the unbound package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - A flaw was found in unbound in versions prior to 1.10.1. An infinite loop can be created when malformed DNS answers ar...

FreeBSD : adns -- multiple vulnerabilities (08de38d2-e2d0-11ea-9538-0c9d925bbbc0)

Ian Jackson and the adns project reports : Vulnerable applications: all adns callers. Exploitable by: the local recursive resolver. Likely worst case: Remote code execution. Vulnerable applications: those that make SOA queries. Exploitable by: upstream DNS data sources. Likely worst case: DoS cra...

CVE-2019-6469: Reachable Assertion

An error in the EDNS Client Subnet ECS feature for recursive resolvers can cause BIND to exit with an assertion failure when processing a response that has malformed RRSIGs. Versions affected: BIND 9.10.5-S1 - 9.11.6-S1 of BIND 9 Supported Preview Edition...

DNS Flag Day & Akamai

Written by Jon Reed & Barry Greene DNS Flag Day is an industry event that promotes the adoption of the most up-to-date DNS features and ensures that non-standards-compliant servers don't negatively impact the global performance of the Internet. The 2019 DNS Flag Day will remove a number of...

Denial Of Service

BIND is susceptible to denial of service. The vulnerability is possible because it does not properly handle resource records with a large RDATA value, allowing the attacker to create malicious DNS resource records causing recursive resolver or secondary server to exit unexpectedly with an asserti...
