OpenSSL Heartbeat 'Heartbleed' Vulnerability

Lexmark Security Advisory:

Revision: 1.1 Last update: 18 April 2014 Public Release Date: 15 April 2014


OpenSSL Heartbeat Vulnerability Lexmark has learned of a vulnerability in certain versions of the open-source OpenSSL Library that allows unauthenticated access to private memory of printer devices and computer systems. Multiple Lexmark products are affected by this vulnerability. This advisory will be updated as additional information becomes available.




On April 8, 2014 a vulnerability, commonly referred to as “Heartbleed” was announced in the open-source software package OpenSSL. Some versions of OpenSSL contain a flaw in its implementation of the TLS/DTLS heartbeat functionality. This flaw allows an attacker to access private memory of the application that uses the vulnerable OpenSSL library. This access may lead to the disclosure and compromise of authentication credentials (usernames/passwords, private keys, etc.) as well as user data.

Releases prior to .P231 were not affected.

Only the devices listed above are affected, all other devices are not affected.

The benefit of generating new device keys and certificates is dependent on the environment in which the device is deployed. If device certificates (self-signed and/or PKI signed) are utilize within the environment, it is suggested that customers evaluate the need to generate new keys and certificates based on their internal risk assessment.


Lexmark recommends a firmware update if your device has affected firmware.

Obtaining Updated Software

To obtain firmware that resolves this issue or if you have special code, please contact Lexmark’s Technical Support Center at to find your local support center.
