Synopsis
tboot bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated tboot packages that fix multiple bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.
Description
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)
This update also fixes the following bugs:
- 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. (BZ#732439)
- 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. (BZ#754345)
All users of tboot are advised to upgrade to these updated packages, which fix
these bugs and adds these enhancements.
Solution
Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
