Advisory Release Date: 2015-01-15 14:55 Pacific
Severity: Important

Issue Overview:

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 )

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. (CVE-2014-8095 , CVE-2014-8096 , CVE-2014-8099 , CVE-2014-8100 , CVE-2014-8101 , CVE-2014-8102 , CVE-2014-8103 )
