Issue Overview: The DNS message parsing code in named includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected named instance by exploiting this flaw. This...

Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-6.5.6.5)

The version of AOS installed on the remote host is prior to 6.5.6.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.5.6.5 advisory. - Certain DNSSEC aspects of the DNS protocol in RFC 4033, 4034, 4035, 6840, and related RFCs allow remote attackers to cause ...

CISA Warns of Exploitable Vulnerabilities in Popular BIND 9 DNS Software

The Internet Systems Consortium ISC has released patches to address multiple security vulnerabilities in the Berkeley Internet Name Domain BIND 9 Domain Name System DNS software suite that could be exploited to trigger a denial-of-service DoS condition. "A cyber threat actor could exploit one of...

Assertion Failure

libbind9.so is vulnerable to an Assertion Failure. The vulnerability is due to improper handling of client queries that trigger serving stale data and require lookups in local authoritative zone data, allowing an attacker to disrupt the normal operation of the BIND 9 service, potentially causing ...

ISC Releases Security Advisories for BIND 9

The Internet Systems Consortium ISC released security advisories to address vulnerabilities affecting multiple versions of ISC’s Berkeley Internet Name Domain BIND 9.

CVE-2024-4076

Client queries that trigger serving stale data and that also require lookups in local authoritative zone data may result in an assertion failure. 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...

CVE-2024-0760

A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0...

CVE-2024-1737

Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname of any RTYPE can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name. This issue affects BIND 9 versions 9.11.0 throug...
