A malicious X Server could send specially crafted data to X clients, which allowed for triggering
crashes, or privilege escalation if this relationship was untrusted or crossed user or permission
level boundaries.

libX11, libXfixes, libXi, libXrandr, libXrender, libXtst, libXv, libXvMC were fixed, specifically:

libX11:
- CVE-2016-7942: insufficient validation of data from the X server allowed out of boundary memory
 read (bsc#1002991)

libXfixes:
- CVE-2016-7944: insufficient validation of data from the X server can cause an integer overflow
 on 32 bit architectures (bsc#1002995)

libXi:
- CVE-2016-7945, CVE-2016-7946: insufficient validation of data from the X server can cause out of
 boundary memory access or endless loops (Denial of Service) (bsc#1002998)

libXtst:
- CVE-2016-7951, CVE-2016-7952: insufficient validation of data from the X server can cause out of
 boundary memory access or endless loops (Denial of Service) (bsc#1003012)

libXv:
- CVE-2016-5407: insufficient validation of data from the X server can cause out of boundary memory
 and memory corruption (bsc#1003017)

libXvMC:
- CVE-2016-7953: insufficient validation of data from the X server can cause a one byte buffer read
 underrun (bsc#1003023)

libXrender:
- CVE-2016-7949, CVE-2016-7950: insufficient validation of data from the X server can cause out of
 boundary memory writes (bsc#1003002)

libXrandr:
- CVE-2016-7947, CVE-2016-7948: insufficient validation of data from the X server can cause out of
