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

  - The PS Interpreter in Ghostscript 9.18 and 9.20 allows
    remote attackers to execute arbitrary code via crafted
    userparams.(CVE-2016-7976)

  - psi/zfile.c in Artifex Ghostscript before 9.21rc1
    permits the status command even if -dSAFER is used,
    which might allow remote attackers to determine the
    existence and size of arbitrary files, a similar issue
    to CVE-2016-7977.(CVE-2018-11645)

  - A flaw was found in the .pdfexectoken and other
    procedures where it did not properly secure its
    privileged calls, enabling scripts to bypass `-dSAFER`
    restrictions. A specially crafted PostScript file could
    disable security protection and then have access to the
    file system, or execute arbitrary
    commands.(CVE-2019-14817)

  - A flaw was found in the setsystemparams procedure where
    it did not properly secure its privileged calls,
    enabling scripts to bypass `-dSAFER` restrictions. A
    specially crafted PostScript file could disable
    security protection and then have access to the file
    system, or execute arbitrary commands.(CVE-2019-14813)

  - A flaw was found in the .setuserparams2 procedure where
    it did not properly secure its privileged calls,
    enabling scripts to bypass `-dSAFER` restrictions. A
    specially crafted PostScript file could disable
    security protection and then have access to the file
    system, or execute arbitrary commands.(CVE-2019-14812)

  - A flaw was found in the .pdf_hook_DSC_Creator procedure
    where it did not properly secure its privileged calls,
    enabling scripts to bypass `-dSAFER` restrictions. A
    specially crafted PostScript file could disable
    security protection and then have access to the file
    system, or execute arbitrary commands.(CVE-2019-14811)

  - libjbig2dec.a in Artifex jbig2dec 0.13, as used in
    MuPDF and Ghostscript, has a NULL pointer dereference
    in the jbig2_huffman_get function in jbig2_huffman.c.
    For example, the jbig2dec utility will crash
    (segmentation fault) when parsing an invalid
    file.(CVE-2017-9216)

  - Artifex jbig2dec 0.13, as used in Ghostscript, allows
    out-of-bounds writes because of an integer overflow in
    the jbig2_build_huffman_table function in
    jbig2_huffman.c during operations on a crafted JBIG2
    file, leading to a denial of service (application
    crash) or possibly execution of arbitrary
    code.(CVE-2017-7975)

  - Artifex jbig2dec 0.13 has a heap-based buffer over-read
    leading to denial of service (application crash) or
    disclosure of sensitive information from process
    memory, because of an integer overflow in the
    jbig2_decode_symbol_dict function in
    jbig2_symbol_dict.c in libjbig2dec.a during operation
    on a crafted .jb2 file.(CVE-2017-7885)

  - Artifex jbig2dec 0.13 allows out-of-bounds writes and
    reads because of an integer overflow in the
    jbig2_image_compose function in jbig2_image.c during
    operations on a crafted .jb2 file, leading to a denial
    of service (application crash) or disclosure of
    sensitive information from process
    memory.(CVE-2017-7976)

  - ghostscript before version 9.21 is vulnerable to a heap
    based buffer overflow that was found in the ghostscript
    jbig2_decode_gray_scale_image function which is used to
    decode halftone segments in a JBIG2 image. A document
    (PostScript or PDF) with an embedded, specially
    crafted, jbig2 image could trigger a segmentation fault
    in ghostscript.(CVE-2016-9601)

  - In Artifex Ghostscript before 9.26, a carefully crafted
    PDF file can trigger an extremely long running
    computation when parsing the file.(CVE-2018-19478)

  - It was found that the .buildfont1 procedure did not
    properly secure its privileged calls, enabling scripts
    to bypass `-dSAFER` restrictions. An attacker could
    abuse this flaw by creating a specially crafted
    PostScript file that could escalate privileges and
    access files outside of restricted
    areas.(CVE-2019-10216)
