Bug#777: nx-libs: incorrect usage of scanf
by Heinrich Schuchardt 15 May '15

15 May '15

package: nx-libs version: head In different parts of the nx-libs library you can find usages of scanf like /* check for MESA_GAMMA environment variable */ gamma = _mesa_getenv("MESA_GAMMA"); if (gamma) { v->RedGamma = v->GreenGamma = v->BlueGamma = 0.0; sscanf( gamma, "%f %f %f", &v->RedGamma, &v->GreenGamma, &v->BlueGamma ); According to cppcheck: scanf without field width limits can crash with huge input data on libc versions older than 2.13-25. Add a field width specifier to fix this problem: %i => %3i Best regards Heinrich Schuchardt

Bug#556: hp-toolbox segfaults when started in x2go MATE session
by erik.devriendt＠telenet.be 15 May '15

Package: nx-libs Version: 3.5.0.27 Distribution: Linux Mint 17 64-bit. hp-toolbox segfaults when started in a x2go MATE session. hp-toolbox is a python script, part of the hplip-gui package in Linux Mint 17. After unsetting the LD_LIBRARY_PATH environment variable, hp-toolbox starts without segfaulting. (hp-toolbox started in a shell in a terminal window).

Bug#123: Fwd: Message with no Package: tag cannot be processed! (nxagent package missing dependancy on Scientific Linux)
by Vincent Gerris 15 May '15

15 May '15

Package: nxagent Hi folks This is aretry of my bug report. Why not just use a bugtracker like trac? I did have a line with Package: . Well, this is another try, the previous content: I use X2Go on Scientific Linux, which is very similar to CentOS. After a recent regular update I encountered a dependancy issue: Error: Package: nxagent-3.5.0.17-3.1.x86_64 (X11_RemoteDesktop_x2go) Requires: xorg-x11-fonts-core The mentioned package seems to only exist on Suse. I use the X2xo repo to install packages, this is the content of my repo file: [X11_RemoteDesktop_x2go] name=X2go - after NoMachine ditched the open version (RHEL_6) type=rpm-md baseurl= http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/ gpgcheck=1 gpgkey= http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/r… enabled=1 Is there an issue with the built? Kind regards, Vincent

Bug#271: nx-3.5.0.20 breaks FreeNX on RPM based system
by Mike Gabriel 15 May '15

15 May '15

Package: nx-libs Version: 3.5.0.20 Tag: rpm-packages Hi Jan, 23:31 < masc88> hello. nx-3.5.0.20 appears to introduce corruption within server side session file and communication protocol 23:32 < masc88> on session resume in conjunction with freenx. is this a known issue? 23:33 < masc88> I had to downgrade to nx-3.5.0.17 to stabilize resuming of sessions obviously there is a problem with FreeNX / X2Go if nx-3.5.0.20 is installed. I assume that the installation is on an RPM based system (because the .deb packages do not have a package named nx).
