The first issue can lead to a denial of service on 32-bit if a backend sends crafted answers, and the second to an alteration of dnsdist’s ACL if the API is enabled, writable and an authenticated user is tricked into visiting a crafted website. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
