Updated gd packages that fix one bug is now available for Red Hat Enterprise Linux 6.
The gd packages provide the gd graphics library. GD allows code to draw images as PNG or JPEG files.
Prior to this update, ,the gd graphics library handled inverted Y coordinates incorrectly, when changing the thickness of a line. As a consequence, lines with changed thickness were drawn incorrectly. This update modifies the underlying code to draw lines with changed thickness correctly.
All users of gd are advised to upgrade to these updated packages, which fix this bug.
