It provides secure encrypted communication between two untrusted hosts over an insecure network. The OpenSSH developers released[1] a new version of OpenSSH which fixes a local vulnerability[2] related to the "UseLogin" option. If this option is enabled, local users may be able to pass arbitrary environment variables to the "login" process. By setting LD_PRELOAD and using a malicious shared library, an attacker might execute arbitrary code as root. Please note that Conectiva Linux does not have the "UseLogin" option enabled by default. Therefore, it's not vulnerable to attacks unless the system administrator has turned it on. SOLUTION It is recommended that all OpenSSH users upgrade their packages. This upgrade will restart the service if it's already running.
