"Included in Log4j 1.2, a logging library for Java, is a SocketServer
class that is vulnerable to deserialization of untrusted data which
can be exploited to remotely execute arbitrary code when combined with
a deserialization gadget when listening to untrusted network traffic
for log data.

For Debian 8 'Jessie', this problem has been fixed in version
1.2.17-5+deb8u1.

We recommend that you upgrade your apache-log4j1.2 packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
