CVE-2020-19861 1 Nlnetlabs 1 Ldns 2022-07-12 5.0 MEDIUM 7.5 HIGH
When a zone file in ldns 1.7.1 is parsed, the function ldns_nsec3_salt_data is too trusted for the length value obtained from the zone file. When the memcpy is copied, the 0xfe - ldns_rdf_size(salt_rdf) byte data can be copied, causing heap overflow information leakage.
CVE-2021-43172 1 Nlnetlabs 1 Routinator 2022-04-25 5.0 MEDIUM 7.5 HIGH
NLnet Labs Routinator prior to 0.10.2 happily processes a chain of RRDP repositories of infinite length causing it to never finish a validation run. In RPKI, a CA can choose the RRDP repository it wishes to publish its data in. By continuously generating a new child CA that only consists of another CA using a different RRDP repository, a malicious CA can create a chain of CAs of de-facto infinite length. Routinator prior to version 0.10.2 did not contain a limit on the length of such a chain and will therefore continue to process this chain forever. As a result, the validation run will never finish, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all.
CVE-2021-43173 1 Nlnetlabs 1 Routinator 2022-01-12 5.0 MEDIUM 7.5 HIGH
In NLnet Labs Routinator prior to 0.10.2, a validation run can be delayed significantly by an RRDP repository by not answering but slowly drip-feeding bytes to keep the connection alive. This can be used to effectively stall validation. While Routinator has a configurable time-out value for RRDP connections, this time-out was only applied to individual read or write operations rather than the complete request. Thus, if an RRDP repository sends a little bit of data before that time-out expired, it can continuously extend the time it takes for the request to finish. Since validation will only continue once the update of an RRDP repository has concluded, this delay will cause validation to stall, leading to Routinator continuing to serve the old data set or, if in the initial validation run directly after starting, never serve any data at all.
CVE-2021-43174 1 Nlnetlabs 1 Routinator 2022-01-12 5.0 MEDIUM 7.5 HIGH
NLnet Labs Routinator versions 0.9.0 up to and including 0.10.1, support the gzip transfer encoding when querying RRDP repositories. This encoding can be used by an RRDP repository to cause an out-of-memory crash in these versions of Routinator. RRDP uses XML which allows arbitrary amounts of white space in the encoded data. The gzip scheme compresses such white space extremely well, leading to very small compressed files that become huge when being decompressed for further processing, big enough that Routinator runs out of memory when parsing input data waiting for the next XML element.
CVE-2019-25037 2 Debian, Nlnetlabs 2 Debian Linux, Unbound 2021-12-03 5.0 MEDIUM 7.5 HIGH
** DISPUTED ** Unbound before 1.9.5 allows an assertion failure and denial of service in dname_pkt_copy via an invalid packet. 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.
CVE-2019-25036 2 Debian, Nlnetlabs 2 Debian Linux, Unbound 2021-12-03 5.0 MEDIUM 7.5 HIGH
** DISPUTED ** Unbound before 1.9.5 allows an assertion failure and denial of service in synth_cname. 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.
CVE-2019-25040 2 Debian, Nlnetlabs 2 Debian Linux, Unbound 2021-12-03 5.0 MEDIUM 7.5 HIGH
** DISPUTED ** 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.
CVE-2019-25041 2 Debian, Nlnetlabs 2 Debian Linux, Unbound 2021-12-03 5.0 MEDIUM 7.5 HIGH
** DISPUTED ** 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.
CVE-2021-41531 1 Nlnetlabs 1 Routinator 2021-10-05 5.0 MEDIUM 7.5 HIGH
NLnet Labs Routinator prior to 0.10.0 produces invalid RTR payload if an RPKI CA uses too large values in the max-length parameter in a ROA. This will lead to RTR clients such as routers to reject the RPKI data set, effectively disabling Route Origin Validation.
CVE-2019-18934 1 Nlnetlabs 1 Unbound 2021-07-21 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-2020-12662 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-07-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-12663 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-02-17 5.0 MEDIUM 7.5 HIGH
Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers.
CVE-2020-10772 2 Nlnetlabs, Redhat 2 Unbound, Enterprise Linux 2020-12-03 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-2019-16866 2 Canonical, Nlnetlabs 2 Ubuntu Linux, Unbound 2020-08-24 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-2016-6173 1 Nlnetlabs 1 Nsd 2017-02-24 7.8 HIGH 7.5 HIGH
NSD before 4.1.11 allows remote DNS master servers to cause a denial of service (/tmp disk consumption and slave server crash) via a zone transfer with unlimited data.
