According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: - `nxdomain-redirect domain;` is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response.(CVE-2023-5517)
A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure during recursive resolution, when both of these features are enabled.This issue affects BIND 9 versions 9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.(CVE-2023-5679)
To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queued for later processing. It was discovered that if the resolver is continuously processing query patterns triggering this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely manner. This in turn enables the list of queued cleanup events to grow infinitely large over time, allowing the configured `max-cache-size` limit to be significantly exceeded.(CVE-2023-6516)
Tenable has extracted the preceding description block directly from the EulerOS bind security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
