An update that solves three vulnerabilities can now be installed.
## Description:
This update for bind fixes the following issues:
Update to 9.16.50:
* Bug Fixes:
* A regression in cache-cleaning code enabled memory use to grow significantly
more quickly than before, until the configured max-cache-size limit was
reached. This has been fixed.
* Using rndc flush inadvertently caused cache cleaning to become less
effective. This could ultimately lead to the configured max-cache-size limit
being exceeded and has now been fixed.
* The logic for cleaning up expired cached DNS records was tweaked to be more
aggressive. This change helps with enforcing max-cache-ttl and max-ncache-
ttl in a timely manner.
* It was possible to trigger a use-after-free assertion when the overmem cache
cleaning was initiated. This has been fixed. New Features:
* Added RESOLVER.ARPA to the built in empty zones.
* Security Fixes:
* It is possible to craft excessively large numbers of resource record types
for a given owner name, which has the effect of slowing down database
processing. This has been addressed by adding a configurable limit to the
number of records that can be stored per name and type in a cache or zone
database. The default is 100, which can be tuned with the new max-types-per-
name option. (CVE-2024-1737, bsc#1228256)
* Validating DNS messages signed using the SIG(0) protocol (RFC 2931) could
cause excessive CPU load, leading to a denial-of-service condition. Support
for SIG(0) message validation was removed from this version of named.
(CVE-2024-1975, bsc#1228257)
* When looking up the NS records of parent zones as part of looking up DS
records, it was possible for named to trigger an assertion failure if serve-
stale was enabled. This has been fixed. (CVE-2024-4076, bsc#1228258)
