<p>This isn't as secure as checking the package signature would be <em>if</em> you previously had our package signing public key, but on another distro you probably don't have that yet, so checking the digest against its copy obtained from this separate website is a best-effort measure.</p>
|
||||
<p>Install the package with <code>rpm -U --nodeps</code>. The <code>--nodeps</code> option is needed to bypass the dependency check on our <code>rocky-release</code> package. In essense, you're manually confirming to <code>rpm</code> that you're installing on a compatible distro.</p>
|
||||
<p>You'll normally install packages from the mirrors, which should just work. However, if there's any issue with the mirrors and you uncomment our <code>baseurl</code> line instead, then on non-Rocky you'll need to use <code>DNF_VAR_sigcontentdir=/pub/sig dnf</code> in place of simply <code>dnf</code>.</p>

<h2 id="summary">Summary<a class="headerlink" href="#summary" title="Permanent link">¶</a></h2>
|
||||
<p>As described by <a href="https://www.openwall.com/lists/oss-security/2023/11/14/4">Intel</a>:</p>
|
||||
<p>Under certain microarchitectural conditions, Intel has identified cases where execution of an instruction (REP MOVSB) encoded with a redundant REX prefix may result in unpredictable system behavior resulting in a system crash/hang, or, in some limited scenarios, may allow escalation of privilege from CPL3 to CPL0.</p>
|
||||
<p>and by <a href="https://access.redhat.com/security/cve/CVE-2023-23583">Red Hat</a>:</p>
|
||||
<p>A security vulnerability was found in some Intel processors. Execution of REP MOVSB instructions with a redundant REX prefix may result in execution continuing at an incorrect EIP address after a micro-architectural event occurs, potentially allowing privilege escalation, information disclosure and/or a denial of service via local access.</p>
|
||||
<p>as well as in <a href="https://www.cve.org/CVERecord?id=CVE-2023-23583">CVE-2023-23583</a>.</p>
|
||||
<p>More detail is available via these <a href="https://www.openwall.com/lists/oss-security/2023/11/14/7">links to Intel's website</a> and in the public disclosure by <a href="https://lock.cmpxchg8b.com/reptar.html">Tavis Ormandy</a> from <a href="https://cloud.google.com/blog/products/identity-security/google-researchers-discover-reptar-a-new-cpu-vulnerability">Google</a>.</p>

|
||||
<p>A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the <code>GLIBC_TUNABLES</code> environment variable. This issue could allow a local attacker to use maliciously crafted <code>GLIBC_TUNABLES</code> environment variables when launching binaries with SUID permission to execute code with elevated privileges.</p>
