-Subject: [PATCH] Limit client cut text length to 1 MB
-
-This patch constrains a client cut text length to 1 MB. Otherwise
-a client could make server allocate 2 GB of memory and that seems to
-be to much to classify it as a denial of service.
-
-The limit also prevents from an integer overflow followed by copying
-an uninitilized memory when processing msg.cct.length value larger
-than SIZE_MAX or INT_MAX - sz_rfbClientCutTextMsg.
-
-This patch also corrects accepting length value of zero (malloc(0) is
-interpreted on differnet systems differently).
-
-CVE-2018-7225
