+<p>Multiple vulnerabilites in ruby2.3, interpreter of object-oriented
+scripting language Ruby, were discovered.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-31799">CVE-2021-31799</a>
+
+    <p>In RDoc 3.11 through 6.x before 6.3.1, as distributed with
+    Ruby through 2.3.3, it is possible to execute arbitrary
+    code via | and tags in a filename.</p></li>
+

+
+    <p>An issue was discovered in Ruby through 2.3.3. A malicious
+    FTP server can use the PASV response to trick Net::FTP into
+    connecting back to a given IP address and port. This
+    potentially makes curl extract information about services
+    that are otherwise private and not disclosed (e.g., the
+    attacker can conduct port scans and service banner extractions).</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2021-32066">CVE-2021-32066</a>
+
+    <p>An issue was discovered in Ruby through 2.3.3. Net::IMAP does
+    not raise an exception when StartTLS fails with an an unknown
+    response, which might allow man-in-the-middle attackers to
+    bypass the TLS protections by leveraging a network position
+    between the client and the registry to block the StartTLS
+    command, aka a "StartTLS stripping attack."</p></li>
+
+</ul>
+
+<p>For Debian 9 stretch, these problems have been fixed in version
+2.3.3-1+deb9u10.</p>
+
+<p>We recommend that you upgrade your ruby2.3 packages.</p>
