(All are from May 13, 2014) (Note that we have not determined whether or not X2Go could actually trigger them. They are however now fixed in the VcXsrv code.)

-    *CVE-2014-0160 "​Heartbleed"​ vulnerability (Note: X2Go Client was only affected by the heartbleed vulnerability when connecting to a an X2Go session broker over HTTPS. Even though X2Go Client uses libssh and cygwin'​s openssh, which both in turn use openssl, they were never affected because the SSH protocol does not contain the SSL heartbeat. For more info on why SSH implementations are not affected, read [[https://​access.redhat.com/​site/​solutions/​786603|Red hat's solution article.]]. The only difference between that solution article and X2Go Client is that the vulnerable library file is ssleay32.dll and the non-affected library files are both libeay32.dll and cygcrypto-1.0.0.dll .) +    *CVE-2014-0160 "​Heartbleed"​ vulnerability (Note: X2Go Client was only affected by the heartbleed vulnerability when connecting to a an X2Go session broker over HTTPS.

     *Compared to 4.0.1.3, bug #229 (support for https broker connections) was fixed. However, it was also fixed in 4.0.1.3+build2. This bugfix is being mentioned here because some users may not be aware of 4.0.1.3+build2. (Ironically,​ the fix was to add ssleay32.dll,​ which means that the heartbleed vulnerability was only ever present in 4.0.1.3+build2.)     *Compared to 4.0.1.3, bug #229 (support for https broker connections) was fixed.

 +===== Noteworthy Windows-Specific Bugs =====
 +
 +  * [[http://​bugs.x2go.org/​cgi-bin/​bugreport.cgi?​bug=108|bug 108]] - Certain specialized applications fail to start (or exhibit font-related bugs) due to the fonts not being installed on the X2Go Client. This can be worked around by using the x2goclient-4.0.2.0-miscfonts-setup.exe installer located here: http://​code.x2go.org/​releases/​binary-win32/​x2goclient/​tmp/​ . If the problem still persists, try using x2goclient-4.0.2.0-fullfonts-setup.exe instead. Note that these installers are a temporary measure until a permanent solution is implemented.
 +  * [[http://​bugs.x2go.org/​cgi-bin/​bugreport.cgi?​bug=109|bug 109]] - x2goclient refuses to start after selecting a nonexistent external X server. To prevent this bug, do not select to use an external X server without specifying ​ the path to an external X server that is actually installed. (The default path usually does not exist.) If you are experiencing this bug, work around it by setting this registry value: HKEY_CURRENT_USER\Software\Obviously Nice\x2goclient\settings\useintx = true
