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)

Some vulnerabilities were discovered in ghostscript, an interpreter for the PostScript language and for PDF.

CVE-2018-19134

The setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type.

CVE-2018-19478

Attempting to open a carefully crafted PDF file results in long-running computation. A sufficiently bad page tree can lead to us taking significant amounts of time when checking the tree for recursion.

For Debian 8 'Jessie', these problems have been fixed in version 9.06~dfsg-2+deb8u13.

We recommend that you upgrade your ghostscript packages.
