CVE-2014-8093: Multiple integer overflows in the GLX extension in XFree86 4.0, X.Org X Window System (aka X11 or X) X11R6....

Multiple integer overflows in the GLX extension in XFree86 4.0, X.Org X Window System (aka X11 or X) X11R6.7, and X.Org Server (aka xserver and xorg-server) before 1.16.3 allow remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request to the (1) __glXDisp_ReadPixels, (2) __glXDispSwap_ReadPixels, (3) __glXDisp_GetTexImage, (4) __glXDispSwap_GetTexImage, (5) GetSeparableFilter, (6) GetConvolutionFilter, (7) GetHistogram, (8) GetMinmax, (9) GetColorTable, (10) __glXGetAnswerBuffer, (11) __GLX_GET_ANSWER_BUFFER, (12) __glXMap1dReqSize, (13) __glXMap1fReqSize, (14) Map2Size, (15) __glXMap2dReqSize, (16) __glXMap2fReqSize, (17) __glXImageSize, or (18) __glXSeparableFilter2DReqSize function, which triggers an out-of-bounds read or write.

Security readout for executives and security teams

This issue is in GLX, the OpenGL extension for X11 display servers. A logged-in remote X11 client could send malformed requests that trigger integer overflows, leading to a server crash and, according to the CVE, possible arbitrary code execution. Business risk is highest for legacy Unix/Linux desktops, VDI, lab, or server environments still running old X.Org/XFree86 components. Exposure is likely limited to systems running affected X11 server versions with GLX reachable by authenticated remote users. Modern systems are less likely affected if their distribution has incorporated the 2014 vendor fixes. Legacy desktop, VDI, engineering workstation, and appliance builds deserve targeted inventory review. Prioritize remediation where old X11 servers support remote or shared graphical sessions. The issue is old and not listed as KEV in the supplied bundle, but possible code execution plus service disruption makes unpatched legacy exposure a meaningful operational risk. Mitigation focus: Upgrade xorg-server to 1.16.3 or a vendor-fixed package release.; Apply relevant distribution advisories such as Debian DSA-3095 or Gentoo GLSA-201504-06.; Reduce or disable remote X11 exposure where operationally feasible..
