color management module of Ghostscript. An attacker could use this
to cause a denial of service (application crash). (CVE-2016-10217)

Kamil Frankowicz discovered a divide-by-zero error in the scan
conversion code in Ghostscript. An attacker could use this to cause
a denial of service (application crash). (CVE-2016-10219)

Kamil Frankowicz discovered multiple NULL pointer dereference errors in
