iucode_tool is a program to manipulate IntelĀ® X86 and X86-64 processor
microcode collections, and to use the kernel facilities to upgrade the
microcode on Intel system processors.
It can load microcode data files in text and binary format, sort, list and
filter the microcodes contained in these files, write selected microcodes to a
new file in binary format, or upload them to the kernel.
It operates on non-free microcode data downloaded directly from Intel or
installed by the intel-microcode package.

iucode-tool (2.1.1-1) unstable; urgency=high
* New upstream release:
+ Fix heap buffer overflow on -tr loader (CVE-2017-0357)
* debian/copyright: update for new upstream release
2016-11-10 - Henrique de Moraes Holschuh <hmh@debian.org>
iucode-tool (2.1-1) unstable; urgency=medium
* New upstream release:
+ The early initramfs cpio archives created by iucode_tool are now
deterministic.  Instead of the current system time, the date of
the latest microcode included in the early initramfs will be used.
+ There is a new option to minimize the size of the early initramfs:
--mini-earlyfw.  This option causes iucode_tool to create a non-
standard cpio archive which is typically 736 bytes smaller.
WARNING: the microcode data file might not be visible to the
regular initramfs when this mode is used.
+ iucode-tool will now create valid early initramfs archives past
year 2038.
+ Change the strategy to add defensive padding to the early-initramfs
archive: add an empty directory entry to the cpio archive in order
to force the correct 16-byte alignment for the microcode data by
default.  For --mini-earlyfs, keep the old strategy of appending
extra NULs to the end of the microcode data file name.
* debian/control: correct build-depends versioning of autoconf, automake.
Correct the minimum required versions of autoconf and automake, which
were bumped by upstream version 2.0.
* debian/compat, rules, control: modernize and enable full hardening
+ update debian/rules copyright date
+ switch to dh-based simplified debian/rules (debhelper v9)
+ opt-in to full hardening for PIE and bindnow
As a side-effect, we now fully honor DEB_*_STRIP, etc.
* debian/watch: add uscan watch file.
Add a debian/watch uscan version 3 watchfile to automatically check the
newest iucode-tool release tarball version, using the "latest" branch of
the iucode/releases gitlab project.
* debian/changelog: fix typos on older entires.
* debian/copyright: switch to DEP-5 format.
