| Doc Text: |
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. In version 1.8.0, a remote attacker could provide a specially crafted APNG (Animated Portable Network Graphics) file. This flaw allows attacker-controlled data within an ignored chunk to be reinterpreted as a new chunk header, leading to a low impact on data integrity and availability. This could result in unexpected application behavior or a denial of service.
