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

  - psi/ztoken.c in Artifex Ghostscript 9.21 mishandles
    references to the scanner state structure, which allows
    remote attackers to cause a denial of service
    (application crash) or possibly have unspecified other
    impact via a crafted PostScript document, related to an
    out-of-bounds read in the igc_reloc_struct_ptr function
    in psi/igc.c.(CVE-2017-11714)

  - The pdf14_open function in base/gdevp14.c in Artifex
    Software, Inc. Ghostscript 9.20 allows remote attackers
    to cause a denial of service (use-after-free and
    application crash) via a crafted file that is
    mishandled in the color management
    module.(CVE-2016-10217)

  - The pdf14_pop_transparency_group function in
    base/gdevp14.c in the PDF Transparency module in
    Artifex Software, Inc. Ghostscript 9.20 allows remote
    attackers to cause a denial of service (NULL pointer
    dereference and application crash) via a crafted
    file.(CVE-2016-10218)

  - This vulnerability has been modified since it was last
    analyzed by the NVD. It is awaiting reanalysis which
    may result in further changes to the information
    provided.(CVE-2016-10219)

  - The gs_makewordimagedevice function in base/gsdevmem.c
    in Artifex Software, Inc. Ghostscript 9.20 allows
    remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via a
    crafted file that is mishandled in the PDF Transparency
    module.(CVE-2016-10220)

  - The fill_threshhold_buffer function in
    base/gxht_thresh.c in Artifex Software, Inc.
    Ghostscript 9.20 allows remote attackers to cause a
    denial of service (heap-based buffer overflow and
    application crash) or possibly have unspecified other
    impact via a crafted PostScript
    document.(CVE-2016-10317)

  - The mem_get_bits_rectangle function in base/gdevmem.c
    in Artifex Software, Inc. Ghostscript 9.20 allows
    remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via a
    crafted file.(CVE-2017-5951)

  - The Ins_IP function in base/ttinterp.c in Artifex
    Ghostscript GhostXPS 9.21 allows remote attackers to
    cause a denial of service (use-after-free and
    application crash) or possibly have unspecified other
    impact via a crafted document.(CVE-2017-9612)

  - The Ins_MDRP function in base/ttinterp.c in Artifex
    Ghostscript GhostXPS 9.21 allows remote attackers to
    cause a denial of service (heap-based buffer over-read
    and application crash) or possibly have unspecified
    other impact via a crafted document.(CVE-2017-9726)

  - The gx_ttfReader__Read function in base/gxttfb.c in
    Artifex Ghostscript GhostXPS 9.21 allows remote
    attackers to cause a denial of service (heap-based
    buffer over-read and application crash) or possibly
    have unspecified other impact via a crafted
    document.(CVE-2017-9727)

  - The Ins_JMPR function in base/ttinterp.c in Artifex
    Ghostscript GhostXPS 9.21 allows remote attackers to
    cause a denial of service (heap-based buffer over-read
    and application crash) or possibly have unspecified
    other impact via a crafted document.(CVE-2017-9739)

  - The gs_alloc_ref_array function in psi/ialloc.c in
    Artifex Ghostscript 9.21 allows remote attackers to
    cause a denial of service (heap-based buffer overflow
    and application crash) or possibly have unspecified
    other impact via a crafted PostScript document. This is
    related to a lack of an integer overflow check in
    base/gsalloc.c.(CVE-2017-9835)
