We apologize for the inconvenience.

Original advisory details:

 It was discovered that Ghostscript improperly handled parameters to
 the rsdparams and eqproc commands. An attacker could use these to
 craft a malicious document that could disable -dSAFER protections,
 thereby allowing the execution of arbitrary code, or cause a denial
 of service (application crash). (CVE-2017-8291)

 Kamil Frankowicz discovered a use-after-free vulnerability in the
 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
 Ghostscript. An attacker could use these to cause a denial of service
 (application crash). (CVE-2016-10220, CVE-2017-5951, CVE-2017-7207)");
