<p>An update that has two security fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for etcd fixes the following issues:
Security
Update to version 3.5.18:</p>
<ul>
<li>Ensure all goroutines created by StartEtcd to exit before
closing the errc</li>
<li>mvcc: restore tombstone index if it's first revision</li>
<li>Bump go toolchain to 1.22.11</li>
<li>Avoid deadlock in etcd.Close when stopping during bootstrapping</li>
<li>etcdutl/etcdutl: use datadir package to build wal/snapdir</li>
<li>Remove duplicated <-s.ReadyNotify()</li>
<li>Do not wait for ready notify if the server is stopping</li>
<li>Fix mixVersion test case: ensure a snapshot to be sent out</li>
<li>*: support custom content check offline in v2store</li>
<li>Print warning message for deprecated flags if set</li>
<li>fix runtime error: comparing uncomparable type</li>
<li>
<p>add tls min/max version to grpc proxy</p>
</li>
<li>
<p>Fixing a configuration data loss bug:
Fillup really really wants that the template and the target file
actually follow the sysconfig format. The current config and the
current template do not fulfill this requirement.
Move the current /etc/sysconfig/etcd to /etc/default/etcd and
install a new sysconfig file which only adds the ETCD_OPTIONS
option, which is actually used by the unit file.
This also makes it a bit cleaner to move etcd to use
--config-file in the long run.</p>
</li>
<li>
<p>Update etcd configuration file based on
https://github.com/etcd-io/etcd/blob/v3.5.17/etcd.conf.yml.sample</p>
