Description

Updated imlib2 packages fix security vulnerabilities:

An out-of-bounds read caused by an off-by-one error in __imlib_MergeUpdate()
in src/lib/updates.c in imlib2 1.4.8 and earlier (CVE-2016-3993).

An out-of-bounds read from colormap in the GIF loader in imlib2 1.4.8 and
earlier can result in denial of service and potential host memory exposure
(CVE-2016-3994).

Attempting to draw a 2x1 ellipse with e.g. imlib_image_draw_ellipse(x, y, 2, 1)
causes a divide-by-zero in imlib2 1.4.8 and earlier, resulting in a denial of
service if an application uses the draw command with untrusted input
(CVE-2011-5326).
