+Subject: [PATCH] gh-97612: Fix shell injection in get-remote-certificate.py
+ (GH-97613)
+
+Fix a shell code injection vulnerability in the
+get-remote-certificate.py example script. The script no longer uses a
+shell to run "openssl" commands. Issue reported and initial fix by
+Caleb Shortt.
+
+Remove the Windows code path to send "quit" on stdin to the "openssl
+s_client" command: use DEVNULL on all platforms instead.
+
+Co-authored-by: Caleb Shortt <caleb@rgauge.com>
+(cherry picked from commit 83a0f44ffd8b398673ae56c310cf5768d359c341)
