the validity of ARGB, JPG, LBM, PNG, PNM, TGA, and TIFF images. If a
user were tricked into viewing or processing a specially crafted image
with an application that uses imlib2, the flaws could be exploited to
execute arbitrary code with the user's privileges.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
