+Subject: [PATCH xserver 1/4] Xi/randr: fix handling of PropModeAppend/Prepend
+
+The handling of appending/prepending properties was incorrect, with at
+least two bugs: the property length was set to the length of the new
+part only, i.e. appending or prepending N elements to a property with P
+existing elements always resulted in the property having N elements
+instead of N + P.
+
+Second, when pre-pending a value to a property, the offset for the old
+values was incorrect, leaving the new property with potentially
+uninitalized values and/or resulting in OOB memory writes.
+For example, prepending a 3 element value to a 5 element property would
+result in this 8 value array:
+  [N, N, N, ?, ?, P, P, P ] P, P
+                            ^OOB write
+
+The XI2 code is a copy/paste of the RandR code, so the bug exists in
+both.
+
+CVE-2023-5367, ZDI-CAN-22153
+
+This vulnerability was discovered by:
+Jan-Niklas Sohn working with Trend Micro Zero Day Initiative
