Description Vasyl Kaigorodov 2015-01-06 07:07:34 EST

It was reported [1] that libpng versions 1.6.9-1.6.15 contain heap overflow vulnerability, that under certain circumstances [2] can allow a controlled write.
Other versions of libpng might be vulnerable as well.

This looks like the upstream commit that fixes this:
