+From ce87eac0325581b600b3093fcd75080df14ccfda Mon Sep 17 00:00:00 2001

+Subject: [PATCH] XRA: Fix an infinite loop
+
+C compilers don't care what size a value was on the wire. Use
+naturally-sized ints, including in dissect_message_channel_mb where we
+would otherwise overflow and loop infinitely.
+
+Fixes #19100
+
+Upstream-Status: Backport [https://gitlab.com/wireshark/wireshark/-/commit/e18d0e369729b0fff5f76f41cbae67e97c2e52e5]
