Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : ghostscript regression (USN-3272-2)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

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.

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:F/RL:OF/RC:ND)
