CVE-2017-16794

CWE-125Published: November 12, 2017· Updated: Jun 17, 2026

5.5
CVSS v3.1

Official Description

The png_load function in lib/png.c in SWFTools 0.9.2 does not properly validate a multiplication of width and bits-per-pixel values, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file, as demonstrated by an erroneous png_load call that occurs because of incorrect integer data types in png2swf.

Technical Analysis

CVE-2017-16794 requires local access, meaning attackers must already have a foothold on the target system.
