<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>It was discovered that there was a information disclosure utility in sudo, a
tool used to provide limited superuser privileges to specific users. A local
unprivileged user may have been able to perform arbitrary directory-existence
tests by exploiting a race condition in sudoedit.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-23239">CVE-2021-23239</a>
<p>The sudoedit personality of Sudo before 1.9.5 may allow a local
unprivileged user to perform arbitrary directory-existence tests by winning
a sudo_edit.c race condition in replacing a user-controlled directory by a
symlink to an arbitrary path.</p></li>
</ul>
<p>For Debian 10 <q>Buster</q>, this problem has been fixed in version
1.8.27-1+deb10u4.</p>
<p>We recommend that you upgrade your sudo packages.</p>
