+Subject: [PATCH] openflow_v6: Prevent infinite loops in too short ofp_stats
+
+The ofp_stats struct length field includes the fixed 4 bytes.
+If the length is smaller than that, report the length error
+and break out. In particular, a value of zero can cause
+infinite loops if this isn't done.
+
+
+(cherry picked from commit 13823bb1059cf70f401892ba1b1eaa2400cdf3db)
+
+Upstream-Status: Backport [https://gitlab.com/wireshark/wireshark/-/commit/39db474f80af87449ce0f034522dccc80ed4153f]
