M. Joonas Pihlaja discovered that imlib2 did not sufficiently verify 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.
