    <title>Apptainer: Lack of Digital Signature Hash Verification</title>
    <synopsis>A vulnerability has been found in Apptainer which could result in the usage of an unexpected of a container.</synopsis>

    <affected>
        <package name="app-containers/apptainer" auto="yes" arch="*">
            <unaffected range="ge">1.1.2</unaffected>

    <background>
        <p>Apptainer is the container system for secure high-performance computing.</p>
    </background>
    <description>
        <p>The Go module &#34;sif&#34; version 2.8.0 and older, which is a statically linked dependency of Apptainer, does not verify that the hash algorithm(s) used are cryptographically secure when verifying digital signatures.</p>
    </description>
    <impact type="low">
        <p>An image whose verification relies on a cryptographically insecure hash algorithm could be replaced, resulting in users using an image other than the one that was expected.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All Apptainer users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=app-containers/apptainer-1.1.2"
        </code>
