MiVoice Office 250 v6.2 SP2 New Features

This section briefly describes the new features, hardware, and enhancements available on the
MiVoice Office 250 when equipped with the v6.2 SP2 software release.

UVM Diagnostic Improvements

The UVM diagnostic improvements supports changing logging level for the UVM application to
help diagnose customer-affecting issues. The logging level for the UVM application can be only
debug or info. The Debug logging level provides logs with the most information. This includes
information that is useful for debugging configuration and hardware integration errors. The Info
logging level includes information about changes in application state values and major
application events. It is available in SysAd and in the AWP.
The debug logging level for UVM is only to be used for specific debugging
activity. It is not recommended to enable debug logging level without prior
consultation with Mitel Product Support. Alarm A150 `Extended APP
Logging is Enabled` will appear until all applications are turned off debug
NOTE
logging level again. The Alarm 150 will not appear on administrator
telephones, it will only appear within System Administration and
Diagnostics, and Message Print

Dirty COW Security Updates

Dirty COW (Dirty copy-on-write) is a computer security vulnerability for the Linux kernel that
affects all Linux-based operating systems. It is a local privilege escalation bug that exploits a
race condition in the implementation of the copy-on-write mechanism in the kernel's
memory-management subsystem.
The MiVoice Office 250 v6.2 SP2 has included a series of fixes to prevent the Dirty COW
vulnerabilities from affecting the system.

New PS1 Hardware Server

The R230 Server supports the MiVoice Office 250 PS1 software, and it is capable of running
the 32-bit Debian 4.0 based distribution with the MiVoice Office 250 components.
