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.
