CVE-2018-5745
Last modified
CVE-2018-5745 is a medium-severity vulnerability rated 4.9/10 on the CVSS scale. "managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. EPSS estimates a 2.26% chance of exploitation in the next 30 days.
