The remote Scientific Linux host is missing one or more security
The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.
An uninitialized memory read issue was found in the way libpng
processed certain PNG images that use the Physical Scale (sCAL)
extension. An attacker could create a specially-crafted PNG image
that, when opened, could cause an application using libpng to crash.
Users of libpng and libpng10 should upgrade to these updated packages,
which contain a backported patch to correct this issue. All running
applications using libpng or libpng10 must be restarted for the update
to take effect.
