CVE ID         : CVE-2017-6362

A double-free vulnerability was discovered in the gdImagePngPtr()

manipulation, which may result in denial of service or potentially the
execution of arbitrary code if a specially crafted file is processed.

For the oldstable distribution (jessie), this problem has been fixed
in version 2.1.0-5+deb8u11.

For the stable distribution (stretch), this problem has been fixed in
version 2.2.4-2+deb9u2.
