Unbound is also vulnerable when compiled + with ECS support, i.e., '--enable-subnet', AND configured + to send ECS information along with queries to upstream name servers, + i.e., at least one of the 'send-client-subnet', + 'client-subnet-zone' or 'client-subnet-always-forward' + options is used. Resolvers supporting ECS need to segregate outgoing + queries to accommodate for different outgoing ECS information. This + re-opens up resolvers to a birthday paradox attack (Rebirthday + Attack) that tries to match the DNS transaction ID in order to cache + non-ECS poisonous replies.</p> + </blockquote> + </body> + </description> + <references> + <cvename>CVE-2025-5994</cvename> + <url>https://nvd.nist.gov/vuln/detail/CVE-2025-5994</url> + </references> + <dates> + <discovery>2025-07-16</discovery> + <entry>2025-07-18</entry> + </dates> + </vuln> + <vuln vid="aeac223e-60e1-11f0-8baa-8447094a420f"> <topic>liboqs -- Secret-dependent branching in HQC</topic> <affects> |
