 Two vulnerabilities have been discovered in libpng:
 The png_user_version_check function contains an out-of-bounds memory access error (libpng 1.6.15 Release Notes) The png_combine_row function contains an integer overflow error, which could result in a heap-based buffer overflow (CVE-2014-9495) Impact :
