<title>Babel: Remote code execution</title>
<synopsis>A vulnerability in Babel could result in remote code execution.</synopsis>
<product type="ebuild">Babel</product>

<bug>786954</bug>
<access>remote</access>
<affected>
<package name="dev-python/Babel" auto="yes" arch="*">
<unaffected range="ge">2.9.1</unaffected>
<vulnerable range="lt">2.9.1</vulnerable>
</package>
</affected>
<background>
<p>Babel is a collection of tools for internationalizing Python applications.</p>
</background>
<description>
<p>Babel does not properly restrict which sources a locale can be loaded from. If Babel loads an attacker-controlled .dat file, arbitrary code execution can be achieved via unsafe Pickle deserialization.</p>
</description>
<impact type="normal">
<p>An attacker with filesystem access and control over the locales Babel loads can achieve code execution.</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Babel users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-python/Babel-2.9.1"
</code>
</resolution>
