Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Kurt Seifried reports :

There is an issue in ImageMagick that is also present in
GraphicsMagick. CVE-2011-3026 deals with libpng memory allocation, and
limitations have been added so that a bad PNG can't cause the system
to allocate a lot of memory and a denial of service. However on
further investigation of ImageMagick, Tom Lane found that PNG malloc
function (Magick_png_malloc) in turn calls AcquireMagickMemory with an
improper size argument.
