+<p>It was discovered that there was a potential remote code execution via
+deserialization in tomcat7, a server for HTTP and Java "servlets".</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-9484">CVE-2020-9484</a>
+
+ <p>When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to
+ 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to
+ control the contents and name of a file on the server; and b) the server is
+ configured to use the PersistenceManager with a FileStore; and c) the
+ PersistenceManager is configured with
+ sessionAttributeValueClassNameFilter="null" (the default unless a
+ SecurityManager is used) or a sufficiently lax filter to allow the attacker
+ provided object to be deserialized; and d) the attacker knows the relative
+ file path from the storage location used by FileStore to the file the
+ attacker has control over; then, using a specifically crafted request, the
+ attacker will be able to trigger remote code execution via deserialization
+ of the file under their control. Note that all of conditions a) to d) must
+ be true for the attack to succeed.</p></li>
+
+</ul>
+
+<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
+7.0.56-3+really7.0.100-1+deb8u1.</p>
+
+<p>We recommend that you upgrade your tomcat7 packages.</p>
