| CVE-2020-19860 | 1 Nlnetlabs | 1 Ldns | 2022-01-27 | 4.3 MEDIUM | 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-2019-25031 | 2 Debian, Nlnetlabs | 2 Debian Linux, Unbound | 2021-12-03 | 4.3 MEDIUM | 5.9 MEDIUM |
| ** DISPUTED ** Unbound before 1.9.5 allows configuration injection in create_unbound_ad_servers.sh upon a successful man-in-the-middle attack against a cleartext HTTP session. NOTE: The vendor does not consider this a vulnerability of the Unbound software. create_unbound_ad_servers.sh is a contributed script from the community that facilitates automatic configuration creation. It is not part of the Unbound installation. | |||||
| CVE-2020-28935 | 1 Nlnetlabs | 2 Name Server Daemon, Unbound | 2021-02-12 | 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-2020-17366 | 1 Nlnetlabs | 1 Routinator | 2020-10-19 | 5.8 MEDIUM | 6.8 MEDIUM |
| 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-2013-5661 | 4 Isc, Nic, Nlnetlabs and 1 more | 4 Bind, Knot Resolver, Nsd and 1 more | 2019-11-08 | 2.6 LOW | 5.9 MEDIUM |
| Cache Poisoning issue exists in DNS Response Rate Limiting. | |||||
| 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. | |||||
