A flaw was discovered in libpng that could result in libpng trying to
free() random memory if certain, unlikely error conditions occurred. If a
carefully-crafted PNG file was loaded by an application linked against
libpng, it could cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the application.
A flaw was discovered in the way libpng handled PNG images containing
"unknown" chunks. If an application linked against libpng attempted to
process a malformed, unknown chunk in a malicious PNG image, it could cause
the application to crash.
