Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests.
