GLSA-201708-10

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.

  - 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 remote host is affected by the vulnerability described in GLSA-201708-10 (jbig2dec: User-assisted execution of arbitrary code)

    Integer overflow errors have been discovered in the       jbig2_decode_symbol_dict, jbig2_build_huffman_table, and       jbig2_image_compose functions of jbig2dec.
  Impact :

    A remote attacker, by enticing a user to open a specially crafted JBIG2       file using an application linked against jbig2dec, could possibly execute       arbitrary code with the privileges of the process or cause a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

Security fix for CVE-2017-7885 CVE-2017-7975

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security issues have been found in the JBIG2 decoder library, which may lead to denial of service, disclosure of sensitive information from process memory or the execution of arbitrary code if a malformed image file (usually embedded in a PDF document) is opened.

CVE-2017-7885 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-2017-7975 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-2017-7976 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.

For Debian 7 'Wheezy', these problems have been fixed in version 0.13-4~deb7u2.

We recommend that you upgrade your jbig2dec packages.
