| CVE-2019-18934 | 3 Fedoraproject, Nlnetlabs, Opensuse | 3 Fedora, Unbound, Leap | 2023-11-07 | 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 | 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-2019-13207 | 1 Nlnetlabs | 1 Name Server Daemon | 2023-11-07 | N/A |
| nsd-checkzone in NLnet Labs NSD 4.2.0 has a Stack-based Buffer Overflow in the dname_concatenate() function in dname.c. | ||||
| CVE-2023-39916 | 1 Nlnetlabs | 1 Routinator | 2023-09-19 | 6.5 Medium |
| NLnet Labs’ Routinator 0.9.0 up to and including 0.12.1 contains a possible path traversal vulnerability in the optional, off-by-default keep-rrdp-responses feature that allows users to store the content of responses received for RRDP requests. The location of these stored responses is constructed from the URL of the request. Due to insufficient sanitation of the URL, it is possible for an attacker to craft a URL that results in the response being stored outside of the directory specified for it. | ||||
| CVE-2023-39915 | 1 Nlnetlabs | 1 Routinator | 2023-09-15 | 7.5 High |
| NLnet Labs’ Routinator up to and including version 0.12.1 may crash when trying to parse certain malformed RPKI objects. This is due to insufficient input checking in the bcder library covered by CVE-2023-39914. | ||||
| CVE-2023-39914 | 1 Nlnetlabs | 1 Bcder | 2023-09-15 | 7.5 High |
| NLnet Labs’ bcder library up to and including version 0.7.2 panics while decoding certain invalid input data rather than rejecting the data with an error. This can affect both the actual decoding stage as well as accessing content of types that utilized delayed decoding. | ||||
| CVE-2020-28935 | 2 Debian, Nlnetlabs | 3 Debian Linux, Name Server Daemon, Unbound | 2023-03-29 | 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-2020-17366 | 1 Nlnetlabs | 1 Routinator | 2023-01-27 | 7.4 High |
| An issue was discovered in NLnet Labs Routinator 0.1.0 through 0.7.1. It allows remote attackers to bypass intended access restrictions or to cause a denial of service on dependent routing systems by strategically withholding RPKI Route Origin Authorisation ".roa" files or X509 Certificate Revocation List files from the RPKI relying party's view. | ||||
| CVE-2023-0158 | 1 Nlnetlabs | 1 Krill | 2023-01-24 | 7.5 High |
| NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the "/rrdp" endpoint. Prior to 0.12.1 a direct query for any existing directory under "/rrdp/", rather than an RRDP file such as "/rrdp/notification.xml" as would be expected, causes Krill to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated. | ||||
| CVE-2020-19861 | 1 Nlnetlabs | 1 Ldns | 2022-10-05 | 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-2009-4008 | 1 Nlnetlabs | 1 Unbound | 2022-10-03 | 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-2009-1755 | 1 Nlnetlabs | 1 Nsd | 2022-10-03 | N/A |
| Off-by-one error in the packet_read_query_section function in packet.c in nsd 3.2.1, and process_query_section in query.c in nsd 2.3.7, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors that trigger a buffer overflow. | ||||
| CVE-2021-43173 | 2 Debian, Nlnetlabs | 2 Debian Linux, Routinator | 2022-08-09 | 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-2021-43172 | 1 Nlnetlabs | 1 Routinator | 2022-04-25 | 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-2021-43174 | 2 Debian, Nlnetlabs | 2 Debian Linux, Routinator | 2022-04-04 | 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-2020-19860 | 1 Nlnetlabs | 1 Ldns | 2022-01-27 | 6.5 Medium |
| When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload. | ||||
| CVE-2021-41531 | 1 Nlnetlabs | 1 Routinator | 2021-10-05 | 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-2017-1000232 | 1 Nlnetlabs | 1 Ldns | 2020-04-01 | N/A |
| A double-free vulnerability in str2host.c in ldns 1.7.0 have unspecified impact and attack vectors. | ||||
| CVE-2017-1000231 | 1 Nlnetlabs | 1 Ldns | 2020-04-01 | N/A |
| A double-free vulnerability in parse.c in ldns 1.7.0 have unspecified impact and attack vectors. | ||||
| CVE-2013-5661 | 4 Isc, Nic, Nlnetlabs and 1 more | 4 Bind, Knot Resolver, Nsd and 1 more | 2019-11-08 | 5.9 Medium |
| Cache Poisoning issue exists in DNS Response Rate Limiting. | ||||
