==========================================================================
Ubuntu Security Notice USN-3272-2
May 16, 2017

ghostscript regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

USN-3272-1 introduced a regression in Ghostscript.

Software Description:
- ghostscript: PostScript and PDF interpreter

Details:

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)
