integer overflow in XRRGetOutputProperty() [CVE-2013-1986 3/4]
If the reported number of properties is too large, the calculations
to allocate memory for them may overflow, leaving us returning less
memory to the caller than implied by the value written to *nitems.
(Same as reported against libX11 XGetWindowProperty by Ilja Van Sprundel)

integer overflow in XRRQueryOutputProperty() [CVE-2013-1986 1/4]
rep.length is a CARD32, while rbytes was a signed int, so
rbytes = sizeof (XRRPropertyInfo) + rep.length * sizeof (long);
could result in integer overflow, leading to an undersized malloc
and reading data off the connection and writing it past the end of
the allocated buffer.
