- Multiple integer overflows in X.org libXrender 0.9.7 and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XRenderQueryFilters, (2) XRenderQueryFormats, and (3) XRenderQueryPictIndexValues functions. (CVE-2013-1987)

- Multiple buffer overflows in the (1) XvQueryAdaptors and (2) XvQueryEncodings functions in X.org libXrender before 0.9.10 allow remote X servers to trigger out-of-bounds write operations via vectors involving length fields. (CVE-2016-7949)
