CVE-2011-2692: Improper Restriction of Operations within the Bounds of a Memory Buffer

July 17, 2011 (updated August 6, 2020)

The png_handle_sCAL function in pngrutil.c in libpng 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.
