+<p>Cache poisoning vulnerabilities were found in node-tar, a Node.js module
+used to read and write portable tar archives, which may result in
+arbitrary file creation or overwrite.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-37701">CVE-2021-37701</a>
+
+    <p>It was discovered that node-tar performed insufficient symlink
+    protection, thereby making directory cache vulnerable to poisoning
+    using symbolic links.</p>
+
+    <p>Upon extracting an archive containing a directory `foo/bar` followed
+    with a symbolic link `foo\\bar` to an arbitrary location, node-tar
+    would extract arbitrary files into the symlink target, thus allowing
+    arbitrary file creation and overwrite.</p>
+
+    <p>Moreover, on case-insensitive filesystems, a similar issue occurred
+    with a directory `FOO` followed with a symbolic link `foo`.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-37712">CVE-2021-37712</a>
+
+    <p>Similar to <a href="https://security-tracker.debian.org/tracker/CVE-2021-37701">CVE-2021-37701</a>, a specially crafted tar archive
+    containing two directories and a symlink with names containing
+    unicode values that normalized to the same value, would bypass
+    node-tar's symlink checks on directories, thus allowing arbitrary
+    file creation and overwrite.</p></li>
+
+</ul>
+
+<p>For Debian 10 buster, these problems have been fixed in version
+4.4.6+ds1-3+deb10u2.</p>
+
+<p>We recommend that you upgrade your node-tar packages.</p>
