RHBA-2015:1282 - Bug Fix Advisory

Topic

Updated hplip packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

The hplip packages contain the Hewlett-Packard Linux Imaging and Printing
Project (HPLIP), which provides drivers for Hewlett-Packard printers and
multi-function peripherals.

The hplip packages have been upgraded to upstream version 3.14.6, which provides
a number of bug fixes and enhancements over the previous version, including
hardware enablement and new functionality, such as the Service Location Protocol
(SLP) discovery feature. (BZ#1077121)

This update also fixes the following bugs:

• Previously, HPLIP did not correctly handle CUPS denying a requested operation,

such enabling or disabling a printer. As a consequence, operating HP Device
Manager as a non-root user did not prompt for the root password when the root
password was required for an operation. With this update, the password callback
is correctly implemented, and operating HP Device Manager as non-root user now
always prompts for the root password when required. (BZ#682814)

• Prior to this update, the use of an uninitialized value could produce

incorrect output from the hpcups driver. The underlying source code has been
modified to initialize the value before it is used, and the described unexpected
behavior is therefore prevented. (BZ#876066)

Users of hplip are advised to upgrade to these updated packages, which fix these
bugs and add these enhancements.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
