+Subject: [PATCH] render: Avoid 0 or less animated cursors
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Animated cursors use a series of cursors that the client can set.
+
+By default, the Xserver assumes at least one cursor is specified
+while a client may actually pass no cursor at all.
+
+That causes an out-of-bound read creating the animated cursor and a
+crash of the Xserver:
+
+ | Invalid read of size 8
+ |    at 0x5323F4: AnimCursorCreate (animcur.c:325)
+ |    by 0x52D4C5: ProcRenderCreateAnimCursor (render.c:1817)
+ |    by 0x52DC80: ProcRenderDispatch (render.c:1999)
+ |    by 0x4A1E9D: Dispatch (dispatch.c:560)
+ |    by 0x4B0169: dix_main (main.c:284)
+ |    by 0x4287F5: main (stubmain.c:34)
+ |  Address 0x59aa010 is 0 bytes after a block of size 0 alloc'd
+ |    at 0x48468D3: reallocarray (vg_replace_malloc.c:1803)
+ |    by 0x52D3DA: ProcRenderCreateAnimCursor (render.c:1802)
+ |    by 0x52DC80: ProcRenderDispatch (render.c:1999)
+ |    by 0x4A1E9D: Dispatch (dispatch.c:560)
+ |    by 0x4B0169: dix_main (main.c:284)
+ |    by 0x4287F5: main (stubmain.c:34)
+ |
+ | Invalid read of size 2
+ |    at 0x5323F7: AnimCursorCreate (animcur.c:325)
+ |    by 0x52D4C5: ProcRenderCreateAnimCursor (render.c:1817)
+ |    by 0x52DC80: ProcRenderDispatch (render.c:1999)
+ |    by 0x4A1E9D: Dispatch (dispatch.c:560)
+ |    by 0x4B0169: dix_main (main.c:284)
+ |    by 0x4287F5: main (stubmain.c:34)
+ |  Address 0x8 is not stack'd, malloc'd or (recently) free'd
+
+To avoid the issue, check the number of cursors specified and return a
+BadValue error in both the proc handler (early) and the animated cursor
+creation (as this is a public function) if there is 0 or less cursor.
+
+CVE-2025-49175
+
+This issue was discovered by Nils Emmerich <nemmerich@ernw.de> and
+reported by Julian Suleder via ERNW Vulnerability Disclosure.
