+Patch Package: OTP 23.3.4.20
+Git Tag: OTP-23.3.4.20
+Date: 2024-03-18
+Trouble Report Id: OTP-18897, OTP-19002
+Seq num: ERIERL-1041
+System: OTP
+Release: 23
+Application: ssh-4.11.1.7
+Predecessor: OTP 23.3.4.19
+
+ Check out the git tag OTP-23.3.4.20, 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.

+ --- POTENTIAL INCOMPATIBILITIES -------------------------------------
+ ---------------------------------------------------------------------
+
+ 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 User's Guide.

+
+ The ssh-4.11.1.7 application can be applied independently of other
+ applications on a full OTP 23 installation.
