The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2863-1 advisory.
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)
Tenable has extracted the preceding description block directly from the SUSE security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
