Detail

A use-after-free vulnerability was discovered in the png_image_free() function in the libpng PNG library, which could lead to denial of service or potentially the execution of arbitrary code if a malformed image is processed.

For the stable distribution (stretch), this problem has been fixed in version 1.6.28-1+deb9u1.

We recommend that you upgrade your libpng1.6 packages.
