Updated tboot packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The tboot packages provide Trusted Boot (tboot), an open source pre- kernel/VMM module, that uses Intel Trusted Execution Technology (Intel TXT) to initialize the launch of operating system kernels and virtual machines.
The tboot package has been upgraded to upstream version 1.7.0, which provides a number of bug fixes and enhancements over the previous version and adds support for future Intel chip sets. (BZ#773406
Prior to this update, increasing binary large objects (BLOB) with lcptools or lcputils utilities could cause a null pointer dereferencing. This update modifies the underlying code so that the pointer now refers to an existing value.
Prior to this update, the tboot module could, under certain circumstances, be enabled on 32-bit platforms. As a consequence, tboot could prevent the kernel from booting. This update restricts tboot to 64-bit platforms.
All users of tboot are advised to upgrade to these updated packages, which fix these bugs and adds these enhancements.
