Debian: New dvipng packages fix arbitrary code execution

Dan Rosenberg discovered that in dvipng, a utility that converts DVI files to PNG graphics, several array index errors allow context-dependent attackers, via a specially crafted DVI file, to cause a denial of service (crash of the application), and possibly arbitrary code execution. Updated packages are available from security.debian.org.
