RHEL 7 : ghostscript (RHSA-2019:0229)

high Nessus Plugin ID 121527

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for ghostscript.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0229 advisory.

The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.

Security Fix(es):

* ghostscript: use-after-free in copydevice handling (699661) (CVE-2018-16540)

* ghostscript: access bypass in psi/zdevice2.c (700153) (CVE-2018-19475)

* ghostscript: access bypass in psi/zicc.c (700169) (CVE-2018-19476)

* ghostscript: access bypass in psi/zfjbig2.c (700168) (CVE-2018-19477)

* ghostscript: subroutines within pseudo-operators must themselves be pseudo-operators (700317) (CVE-2019-6116)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Tavis Ormandy (Google Project Zero) for reporting CVE-2019-6116.

Bug Fix(es):

* Previously, ghostscript-9.07-31.el7_6.1 introduced a regression during the standard input reading, causing a /invalidfileaccess in --run-- error. With this update, the regression has been fixed and the described error no longer occurs. (BZ#1665919)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL ghostscript package based on the guidance in RHSA-2019:0229.
