<h3><a href="#key-ssh-update-20240401">SSH Key Update</a></h3>
|
|
|
|
|
<p>On 2024-03-29, a backdoor was discovered in the
|
|
|
|
|
<a href="https://git.tukaani.org/?p=xz.git">xz-utils</a>
|
|
|
|
|
software. Inferencium systems <strong><em>did</em></strong> have the affected versions of
|
|
|
|
|
this software installed, and the tools were used. The software has since been downgraded to
|
|
|
|
|
the last-known safe version.</p>
|
|
|
|
|
<p>After extensive research, it
|
|
|
|
|
<a href="https://gist.github.com/thesamesam/223949d5a074ebc3dce9ee78baad9e27">has been discovered</a>
|
|
|
|
|
that specific criteria must be met for the backdoor to be effective. Based on
|
|
|
|
|
<strong><em>what is known</em></strong>, Inferencium systems are unaffected by this attack
|
|
|
|
|
for the following reasons:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>Inferencium systems run Gentoo Linux, which does not include Debian and Red Hat
|
|
|
|
|
OpenSSH patches.</li>
|
|
|
|
|
<li>Inferencium systems use musl libc, not glibc. As musl does not support glibc's
|
|
|
|
|
non-standard <code>IFUNC</code> functionality, the backdoor cannot run.</li>
|
|
|
|
|
<li>Inferencium systems use Clang as the system compiler, and lld as the system
|
|
|
|
|
linker, not GCC and ld.</li>
|
|
|
|
|
<li>Inferencium systems use OpenRC as the init system, not systemd. libsystemd and
|
|
|
|
|
systemd-notify do not work with OpenRC.</li>
|
|
|
|
|
</ul>
|
|
|
|
|
<p>The <em>only</em> criteria met by Inferencium systems is amd64 as the system
|
|
|
|
|
architecture; this is not enough for the backdoor to be effective. Even if all criteria
|
|
|
|
|
other than running glibc were met, Inferencium systems would still be unaffected by this
|
|
|
|
|
attack due to musl not supporting the required <code>IFUNC</code> functionality.</p>
|
|
|
|
|
<p><strong>Despite the evidence, it is unknown exactly what this malicious code does and is
|
|
|
|
|
capable of in entirety. As a precautionary measure, I have generated a new SSH key and
|
|
|
|
|
classifed the previous key as compromised. You can find my new key on the
|
|
|
|
|
<a href="key.xhtml#ssh-current-2">Key webpage</a>.</strong></p>
|
|
|
|
|
<p>There is no evidence that my previous key was compromised, so this is entirely a
|
|
|
|
|
precautionary measure. All files and Git commits, tags, and releases signed with the
|
|
|
|
|
previous key, even after discovery of the backdoor, up to 2024-04-01, are secure and validly
|
|
|
|
|
signed by me; the key should not be trusted after this date.</p>

can be used to access the source code.</p>
|

<p>Due to terms of service restrictions, proprietary code and related repositories, such as

firmware, are unable to be mirrored to Codeberg.</p>
