programmatic graphics creation and manipulation, suffers of a
signedness vulnerability which may result in a heap overflow when
processing specially crafted compressed gd2 data. A remote attacker
can take advantage of this flaw to cause an application using the
libgd2 library to crash, or potentially, to execute arbitrary code
with the privileges of the user running the application."
