The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before
1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before
1.5.4 does not properly handle invalid sCAL chunks, which allows
remote attackers to cause a denial of service (memory corruption and
application crash) or possibly have unspecified other impact via a
crafted PNG image that triggers the reading of uninitialized memory.
