The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.
A buffer overflow flaw was found in the way libpng processed certain
PNG image files. An attacker could create a specially crafted PNG
image that, when opened, could cause an application using libpng to
crash or, potentially, execute arbitrary code with the privileges of
the user running the application. (CVE-2011-2690)
Note: The application behavior required to exploit CVE-2011-2690 is
rarely used. No application shipped with Scientific Linux behaves this
way, for example.
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 should upgrade to these updated packages, which
contain backported patches to correct these issues. All running
applications using libpng must be restarted for the update to take
