Description

The png_handle_cHRM function in pngrutil.c in libpng 1.5.4, when color-correction support is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a malformed PNG image containing a cHRM chunk associated with a certain zero value.
