In Artifex Ghostscript before 9.26, a carefully crafted PDF file can trigger an extremely long running computation when parsing the file.

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 :

  - 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)

  - In ghostscript before version 9.50, 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)

  - The Ins_MIRP 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-2017-9611)

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)

  - 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)

  - 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)

  - 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 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)

  - 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)

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.

Several vulnerabilities were discovered in Ghostscript, the GPL PostScript/PDF interpreter, which may result in denial of service or the execution of arbitrary code if a malformed Postscript file is processed (despite the -dSAFER sandbox being enabled).

This update rebases ghostscript for stretch to the upstream version 9.26 which includes additional changes.

The version of Artifex Ghostscript installed on the remote Windows host is prior to 9.26. It is, therefore, affected by multiple vulnerabilities.
