27 November 2017

OptiPNG could be made to crash or run programs as your login if it opened a specially crafted file.



  • optipng - advanced PNG (Portable Network Graphics) optimizer


It was discovered that OptiPNG incorrectly handled memory. A remote
attacker could use this issue with a specially crafted image file to cause
OptiPNG to crash, resulting in a denial of service, or possibly execute
arbitrary code.
