Digital Signature of Software Upgrade Files
v1.1
NOTE: This bulletin was reissued at version 1.1 to remove the Phaser 3635MFP. An issue with the Phaser 3635MFP will be resolved in a future version of this bulletin.

The Xerox products Phaser 3600, Phasers 4600/4620 and the WorkCentre 3550 were shipped without the ability to accept software upgrade files with digital signatures. The ability to accept only software upgrade files with digital signatures has been added for the indicated products. In addition, the indicated products now include the software upgrade setting in the Configuration Report and have added the capability to enable/disable software upgrade via SNMP.

Firmware solutions that will now only accept software upgrades files with digital signatures have been provided. These solutions are designed to be installed by the customer. The firmware solutions can be accessed via the links below or via the links in this bulletin announcement on the Xerox Security Site.
