Multiple Array index errors leading to heap-based buffer OOB write flaws were found in the libX11, Core X11 protocol client library. When a X client is connected to a malcicious X server , (modified to return invalid values), it can cause arbirary code execution with the privileges of the user running the X client. Affected functions: XAllocColorCells(), _XkbReadGetDeviceInfoReply(), _XkbReadGeomShapes(), _XkbReadGetGeometryReply(), _XkbReadKeySyms(), _XkbReadKeyActions(), _XkbReadKeyBehaviors(), _XkbReadModifierMap(), _XkbReadExplicitComponents(), _XkbReadVirtualModMap(), _XkbReadGetNamesReply(), _XkbReadGetMapReply(), _XimXGetReadData(), XListFonts(), XListExtensions()
