CVE-2017-15105 describes a flaw in Unbound versions prior to 1.6.8, where improper validation of wildcard-synthesized NSEC records could lead to incorrect non-existence proofs for existing wildcard records or acceptance of invalid NODATA proofs. This vulnerability affects various distributions of Unbound, including those from Canonical, Debian, and NLnet Labs. Rated as Medium severity (CVSS 5.3), this vulnerability is network-exploitable with low attack complexity and no user interaction required, potentially leading to a low impact on integrity by providing incorrect DNS resolution. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) or significant community discussion or media coverage has been observed for this CVE.
