Systems Affected

All LANTIME firmware versions before 7.08.016 are affected by the corresponding vulnerabilities. The LANTIME firmware is used by all devices of the LANTIME M series (M100, M150, M200, M250, M300, M320, M400, M450, M600, M900) as well as all devices of the LANTIME IMS series (M500, M1000, M1000S, M2000S, M3000, M3000S, M4000) and the SyncFire product family (SF1000, SF1100, SF1200, SF1500) and LANTIME CPU Expansions (LCES).

Whether and to what extent individual clients or LANTIME systems are vulnerable depends on the individual configuration, network infrastructure, and other factors, and it is therefore not possible to provide a general statement on how vulnerable a given system in use actually is.

Possible Security Measures

The relevant security updates are included in the LANTIME firmware versions 7.08.016(-light). Updating to these versions eliminates the listed vulnerabilities.

Download the latest LANTIME firmware at:

• Meinberg LANTIME Firmware

All updates are now available for Meinberg customers. An update of the LANTIME firmware to the version 7.08.016 respectively 7.08.016-light is recommended. Clients who cannot install version 7.08.016 should install version 7.08.016-light instead.
