REDHAT-BUG-608644
First published: Mon Jun 28 2010(Updated: )
A memory leak was found in the way libpng processed malformed Portable Network Graphics (PNG) images with Physical Scale (sCAL) extension. A remote attacker could create a specially-crafted PNG image and trick the local user into opening it in an application, using the libpng library, leading to denial of service (relevant libpng-based application crash).
