Arch Linux Security Advisory ASA-201711-30 ========================================== Severity: Low Date : 2017-11-27 CVE-ID : CVE-2017-15091 Package : powerdns Type : access restriction bypass Remote : Yes Link : https://security.archlinux.org/AVG-519 Summary ======= The package powerdns before version 4.0.5-1 is vulnerable to access restriction bypass. Resolution ========== Upgrade to 4.0.5-1. # pacman -Syu "powerdns>=4.0.5-1" The problem has been fixed upstream in version 4.0.5. Workaround ========== None. Description =========== An issue has been found in the API component of PowerDNS Authoritative < 4.0.5, where some operations that have an impact on the state of the server are still allowed even though the API has been configured as read-only via the 'api-readonly' keyword. This missing check allows an attacker with valid API credentials could flush the cache, trigger a zone transfer or send a NOTIFY. Impact ====== A remote, authenticated attacker can flush the cache, trigger a zone transfer or send a NOTIFY through the API even though it was configured as read-only.
