| CVE-2020-10772 | 2 Nlnetlabs, Redhat | 2 Unbound, Enterprise Linux | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2019-18934 | 3 Fedoraproject, Nlnetlabs, Opensuse | 3 Fedora, Unbound, Leap | 2023-11-07 | 6.8 MEDIUM | 7.3 HIGH |
| 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. | |||||
| CVE-2019-16866 | 2 Canonical, Nlnetlabs | 2 Ubuntu Linux, Unbound | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2020-28935 | 2 Debian, Nlnetlabs | 3 Debian Linux, Name Server Daemon, Unbound | 2023-03-29 | 2.1 LOW | 5.5 MEDIUM |
| NLnet Labs Unbound, up to and including version 1.12.0, and NLnet Labs NSD, up to and including version 4.3.3, contain a local vulnerability that would allow for a local symlink attack. When writing the PID file, Unbound and NSD create the file if it is not there, or open an existing file for writing. In case the file was already present, they would follow symlinks if the file happened to be a symlink instead of a regular file. An additional chown of the file would then take place after it was written, making the user Unbound/NSD is supposed to run as the new owner of the file. If an attacker has local access to the user Unbound/NSD runs as, she could create a symlink in place of the PID file pointing to a file that she would like to erase. If then Unbound/NSD is killed and the PID file is not cleared, upon restarting with root privileges, Unbound/NSD will rewrite any file pointed at by the symlink. This is a local vulnerability that could create a Denial of Service of the system Unbound/NSD is running on. It requires an attacker having access to the limited permission user Unbound/NSD runs as and point through the symlink to a critical file on the system. | |||||
| CVE-2017-15105 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2019-10-09 | 5.0 MEDIUM | 5.3 MEDIUM |
| A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof. | |||||
| CVE-2011-1922 | 1 Nlnetlabs | 1 Unbound | 2017-08-17 | 4.3 MEDIUM | N/A |
| daemon/worker.c in Unbound 1.x before 1.4.10, when debugging functionality and the interface-automatic option are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DNS request that triggers improper error handling. | |||||
| CVE-2009-3602 | 1 Nlnetlabs | 1 Unbound | 2017-08-17 | 7.5 HIGH | N/A |
| Unbound before 1.3.4 does not properly verify signatures for NSEC3 records, which allows remote attackers to cause secure delegations to be downgraded via DNS spoofing or other DNS-related attacks in conjunction with crafted delegation responses. | |||||
| CVE-2014-8602 | 3 Canonical, Debian, Nlnetlabs | 3 Ubuntu Linux, Debian Linux, Unbound | 2016-11-28 | 4.3 MEDIUM | N/A |
| iterator.c in NLnet Labs Unbound before 1.5.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a large or infinite number of referrals. | |||||
| CVE-2009-4008 | 1 Nlnetlabs | 1 Unbound | 2011-06-14 | 5.0 MEDIUM | N/A |
| Unbound before 1.4.4 does not send responses for signed zones after mishandling an unspecified query, which allows remote attackers to cause a denial of service (DNSSEC outage) via a crafted query. | |||||
| CVE-2010-0969 | 1 Nlnetlabs | 1 Unbound | 2011-06-02 | 5.0 MEDIUM | N/A |
| Unbound before 1.4.3 does not properly align structures on 64-bit platforms, which allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors. | |||||
