The XGetImage function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges via vectors involving image type and geometry, which triggers out-of-bounds read operations. La función XGetImage en X.org libX11 en versiones anteriores a 1.6.4 podría permitir a servidores remotos X obtener privilegios a través de vectores que involucran tipo de imagen y geometría, que desencadena operaciones de lectura fuera de límites. • http://www.openwall.com/lists/oss-security/2016/10/04/2 http://www.openwall.com/lists/oss-security/2016/10/04/4 http://www.securityfocus.com/bid/93363 http://www.securitytracker.com/id/1036945 https://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=8ea762f94f4c942d898fdeb590a1630c83235c17 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMCVDXMFPXR7QGMKDG22WPPJCXH2X3L7 https://lists.x.org/archives/xorg-announce/2016-October/002720.html https://security.g • CWE-264: Permissions, Privileges, and Access Controls CWE-787: Out-of-bounds Write •
