+ Check out the git tag OTP-26.2.1, and build a full OTP system
+ including documentation. Apply one or more applications from this
+ build as patches to your installation using the 'otp_patch_apply'
+ tool. For information on install requirements, see descriptions for
+ each application version below.

+
+  OTP-18897    Application(s): ssh
+
+               With this change (being response to CVE-2023-48795),
+               ssh can negotiate "strict KEX" OpenSSH extension with
+               peers supporting it; also
+               '[email protected]' algorithm becomes a
+               less preferred cipher.
+
+               If strict KEX availability cannot be ensured on both
+               connection sides, affected encryption modes(CHACHA and
+               CBC) can be disabled with standard ssh configuration.
+               This will provide protection against vulnerability, but
+               at a cost of affecting interoperability. See
+               Configuring algorithms in SSH.
