From: Peter Marko <peter.marko@siemens.com>

Per [1]:
* The vulnerable code originates from the third-party libpng-apng patch,
which adds APNG support to libpng 1.6.x.
* Upstream libpng 1.6.x (without the apng patch) is not affected.

As Yocto never included libpng-apng patch, we can ignore this CVE.
