Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited Debian_linux, Unbound 9.8
2021-04-27 CVE-2019-25040 Unbound before 1.9.5 allows an infinite loop via a compressed name in dname_pkt_copy. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited Debian_linux, Unbound 7.5
2021-04-27 CVE-2019-25042 Unbound before 1.9.5 allows an out-of-bounds write via a compressed name in rdata_copy. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited Debian_linux, Unbound 9.8
2021-04-27 CVE-2019-25041 Unbound before 1.9.5 allows an assertion failure via a compressed name in dname_pkt_copy. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited Debian_linux, Unbound 7.5
2024-02-14 CVE-2023-50387 Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. Fedora, Bind, Windows_server_2008, Windows_server_2012, Windows_server_2016, Windows_server_2019, Windows_server_2022, Windows_server_2022_23h2, Knot_resolver, Unbound, Recursor, Enterprise_linux, Dnsmasq 7.5
2019-10-03 CVE-2019-16866 Unbound before 1.9.4 accesses uninitialized memory, which allows remote attackers to trigger a crash via a crafted NOTIFY query. The source IP address of the query must match an access-control rule. Ubuntu_linux, Unbound 7.5
2019-11-19 CVE-2019-18934 Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration. Fedora, Unbound, Leap 7.3
2020-05-19 CVE-2020-12662 Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records. Ubuntu_linux, Debian_linux, Fedora, Unbound, Leap 7.5
2020-05-19 CVE-2020-12663 Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers. Ubuntu_linux, Debian_linux, Fedora, Unbound, Leap 7.5
2020-11-27 CVE-2020-10772 An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound. Unbound 7.5
