Overview

Affected versions of this package are vulnerable to Out-of-Bounds. In SWFTools 0.9.2, the png_load function in lib/png.c does not properly validate an alloclen_64 multiplication of width and height values, which allows remote attackers to cause a denial of service (integer overflow, heap-based buffer overflow, and application crash) or possibly have unspecified other impact via a crafted PNG file.
