Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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: superexec operator is available (700585)
(CVE-2019-3835)

* ghostscript: forceput in DefineResource is still accessible (700576)
(CVE-2019-3838)

* ghostscript: missing attack vector protections for CVE-2019-6116
(CVE-2019-3839)

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to

"According to the versions of the ghostscript package installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - Ghostscript is a set of software that provides a
    PostScript interpreter, a set of C procedures (the
    Ghostscript library, which implements the graphics
    capabilities in the PostScript language) and an
    interpreter for Portable Document Format (PDF) files.
    Ghostscript translates PostScript code into many
    common, bitmapped formats, like those understood by
    your printer or screen. Ghostscript is normally used to
    display PostScript files and to print PostScript files
    to non-PostScript printers.Security Fix(es):It was
    found that the forceput operator could be extracted
    from the DefineResource method. A specially crafted
    PostScript file could use this flaw in order to, for
    example, have access to the file system outside of the
    constrains imposed by -dSAFER.(CVE-2019-3838)t was
    found that the superexec operator was available in the
    internal dictionary. A specially crafted PostScript
    file could use this flaw in order to, for example, have
    access to the file system outside of the constrains
    imposed by -dSAFER.(CVE-2019-3835)It was found that
    ghostscript could leak sensitive operators on the
    operand stack when a pseudo-operator pushes a
    subroutine. A specially crafted PostScript file could
    use this flaw to escape the -dSAFER protection in order
    to, for example, have access to the file system outside
    of the SAFER constraints.(CVE-2019-6116)It was found
    that some privileged operators remained accessible from
    various places after the CVE-2019-6116 fix. A specially
    crafted PostScript file could use this flaw in order
    to, for example, have access to the file system outside
    of the constrains imposed by -dSAFER.(CVE-2019-3839)

score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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: superexec operator is available (700585)
(CVE-2019-3835)

* ghostscript: forceput in DefineResource is still accessible (700576)
(CVE-2019-3838)

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

Bug Fix(es) :

* ghostscript: Regression: double comment chars '%%' in gs_init.ps
leading to missing metadata (BZ#1673915)"
