SUSE-SU-2024:0590-1: Security update for bind
This update for bind fixes the following issues: Update to release 9.16.48: Feature Changes: The IP addresses for B.ROOT-SERVERS.NET have been updated to 170.247.170.2 and 2801:1b8:10::b. Security Fixes: Validating DNS messages containing a lot of DNSSEC signatures could cause excessive CPU load, leading to a denial-of-service condition. This has been fixed. (CVE-2023-50387) [bsc#1219823] Preparing an NSEC3 closest encloser proof could cause excessive CPU load, leading to a denial-of-service condition. This has been fixed. (CVE-2023-50868) [bsc#1219826] Parsing DNS messages with many different names could cause excessive CPU load. This has been fixed. (CVE-2023-4408) [bsc#1219851] Specific queries could cause named to crash with an assertion failure when nxdomain-redirect was enabled. This has been fixed. (CVE-2023-5517) [bsc#1219852] A bad interaction between DNS64 and serve-stale could cause named to crash with an assertion failure, when both of these features were enabled. This has been fixed. (CVE-2023-5679) [bsc#1219853] Query patterns that continuously triggered cache database maintenance could cause an excessive amount of memory to be allocated, exceeding max-cache-size and potentially leading to all available memory on the host running named being exhausted. This has been fixed. (CVE-2023-6516) [bsc#1219854] Removed Features: Support for using AES as the DNS COOKIE algorithm (cookie-algorithm aes;) has been deprecated and will be removed in a future release. Please use the current default, SipHash-2-4, instead.
