Fedora 27: 2017-60c4aa0e01 Moderate: nx-libs Timingsafe Memcmp Issue

fedora
Calendar Grey March 6, 2018
Dist Fedora Esm H88
Enhance the handling of X.Org socket overrides and address the timingsafe_memcmp vulnerability, resulting in better connection efficiency for nx-libs.
nx-libs 3.5.0.33: - Don't allow overriding of X.Org Server UNIX sockets via TEMP/NX_TEMP environment variables

Summary

NX is a software suite which implements very efficient compression of

the X11 protocol. This increases performance when using X

applications over a network, especially a slow one.

This package provides the core nx-X11 libraries customized for

nxagent/x2goagent.

nx-libs 3.5.0.33: - Don't allow overriding of X.Org Server UNIX sockets via

TEMP/NX_TEMP environment variables. Fixes problems on machines that use

pam_tempdir.so. - Fix CVE-2017-2624 (timingsafe_memcmp) by Ulrich Sibiller. -Potentially improve LAN- and WAN-type connection speed settings scenarios.

Includes a regression fix for VPN connections by Simon Matter. - Fix problems in

mate-color-picker and potentially also other applications that make heavy use of

RENDER trapezoids. x2goserver 4.0.1.22: - Fixed overzealous nxagent socket

removal. - Keyboard mapping fixes, including preparation for usage with

Arctica's nx-libs version (not supported in this version of X2Go Server, yet). -Support for Devuan and RT OS full desktop session spawning. - Always use short

host name, don't rely on ${HOSTNAME} variable. Compatibility with non-bash

login shells. - Spawn full desktop sessions with a new dbus user session

instance. - Finnish translation update. - Added support for LXQt full desktop

sessions. - New command: x2golistshadowsessions.
