These issues require connection to a malicious X server to trigger the bugs in client libraries.

Security issues fixed:

 *

 CVE-2013-1981: Multiple integer overflows in X.org libX11 allowed X servers to trigger allocation of insufficient memory and a buffer
 overflow via vectors related to the (1) XQueryFont, (2)
_XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5)
XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8)
XGetKeyboardMapping, (9) XGetWindowProperty, (10) XGetImage, (11)
LoadColornameDB, (12) XrmGetFileDatabase, (13) _XimParseStringFile,
 or (14) TransFileName functions.

 *

 CVE-2013-1997: Multiple buffer overflows in X.org libX11 allowed X servers to cause a denial of service (crash) and possibly execute arbitrary code via crafted length or index values to the (1)
XAllocColorCells, (2) _XkbReadGetDeviceInfoReply, (3) _XkbReadGeomShapes,
(4) _XkbReadGetGeometryReply, (5) _XkbReadKeySyms, (6) _XkbReadKeyActions,
(7) _XkbReadKeyBehaviors, (8) _XkbReadModifierMap, (9)
_XkbReadExplicitComponents, (10) _XkbReadVirtualModMap, (11)
_XkbReadGetNamesReply, (12) _XkbReadGetMapReply, (13) _XimXGetReadData,
(14) XListFonts, (15) XListExtensions, and (16) XGetFontPath functions.

 *

 CVE-2013-2004: The (1) GetDatabase and (2) _XimParseStringFile functions in X.org libX11 did not restrict the recursion depth when processing directives to include files, which allowed X servers to cause a denial of service (stack consumption) via a crafted file.
