xorg-x11-server: out of bounds access due to not validating length or offset values in XC-MISC extension
The SProcXCMiscGetXIDList function in the XC-MISC extension in X.Org X Window System (aka X11 or X) X11R6.0 and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length or index value.
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-2014-8091 X.Org X server vulnerabilities
Title: X.Org X server vulnerabilities
Summary: Several security issues were fixed in the X.Org X server.
Ilja van Sprundel discovered a multitude of security issues in the X.Org X
server. An attacker able to connect to an X server, either locally or
remotely, could use these issues to cause the X server to crash or execute
arbitrary code resulting in possible privilege escalation.
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.

tigervnc requires rebuild after Dec-2014 xorg-x11-server CVEs
The Xvnc server (tigervnc-server) and VNC extension for the Xorg server (tigervnc-server-module) are built with xorg-x11-server-source, but have not been rebuilt since the numerous security issues announced in December 2014 (CVE-2014-8091, CVE-2014-8092, CVE-2014-8093, CVE-2014-8094, CVE-2014-8095, CVE-2014-8096, CVE-2014-8097, CVE-2014-8098, CVE-2014-8099, CVE-2014-8100, CVE-2014-8101, CVE-2014-8102, CVE-2014-8103).
Therefore, 1) tigervnc needs to be rebuilt for all supported branches in both Fedora and RHEL, and 2) something needs to be put in place that CVEs in xorg-x11-server also trigger notifications for tigervnc.

CVE-2014-8096 xorg-x11-server: out of bounds access due to not validating length or offset values in XC-MISC extension
SProcXCMiscGetXIDList() call in XC-MISC extension do not check that the lengths and/or indexes sent by the
client are within the bounds specified by the caller or the bounds of
the memory allocated to hold the request read from the client, so could
read or write past the bounds of allocated memory while processing the
request. These calls all occur only after a client has successfully
authenticated itself.
Introduced in X11R6.0 (1994).
