Description

USN-3272-1 fixed vulnerabilities in Ghostscript. This change introduced a regression when the DELAYBIND feature is used with the eqproc command. This update fixes the problem.

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)
