Multiple integer overflow flaws and out-of-bounds write flaws were found
in the way the X.Org server calculated memory requirements for certain X11
core protocol and GLX extension requests. A malicious, authenticated
client could use either of these flaws to crash the X.Org server or,
potentially, execute arbitrary code with root privileges. (CVE-2014-8092,
CVE-2014-8093, CVE-2014-8098)

It was found that the X.Org server did not properly handle SUN-DES-1
(Secure RPC) authentication credentials. A malicious, unauthenticated
client could use this flaw to crash the X.Org server by submitting a
specially crafted authentication request. (CVE-2014-8091)

Multiple out-of-bounds access flaws were found in the way the X.Org server
calculated memory requirements for certain requests. A malicious,
authenticated client could use either of these flaws to crash the X.Org
server, or leak memory contents to the client. (CVE-2014-8097)

An integer overflow flaw was found in the way the X.Org server calculated
memory requirements for certain DRI2 extension requests. A malicious,
authenticated client could use this flaw to crash the X.Org server.
(CVE-2014-8094)
