Note: Firmware versions of Intel ME 3.x thru 10.x, Intel TXE 1.x thru 2.x, and
Intel Server Platform Services 1.x thru 2.X are no longer supported versions.
There is no new general release planned for these versions.
Recommendations:
Intel recommends that users of Intel CSME, SPS and Intel LMS update to the
latest version provided by the system manufacturer that addresses these issues.
Acknowledgements:
These issues were found internally by Intel employees. Intel would like to
thank Julien Lenoir, Marek Augoff-Birman, Yaakov Cohen, Yael Ben Ami and
Yocheved Butterman.
Intel, and nearly the entire technology industry, follows a disclosure practice
called Coordinated Disclosure, under which a cybersecurity vulnerability is
generally publicly disclosed only after mitigations are available.
