+Subject: [PATCH] InitExt.c: Add bounds checks for extension request, event, &
+ error codes
+
+Fixes CVE-2023-3138: X servers could return values from XQueryExtension
+that would cause Xlib to write entries out-of-bounds of the arrays to
+store them, though this would only overwrite other parts of the Display
+struct, not outside the bounds allocated for that structure.

This is being handled with a stable branch version bump which is in
the current test queue: "libx11: upgrade 1.8.5 -> 1.8.6"
