In Artifex MuPDF 1.12.0, the pdf_read_new_xref function in pdf/pdf-xref.c allows remote attackers to cause a denial of service (segmentation violation and application crash) via a crafted pdf file.

Several minor issues have been fixed in mupdf, a lightweight PDF viewer tailored for display of high quality anti-aliased graphics.

CVE-2018-5686

In MuPDF, there was an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF not having been considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted PDF file.

CVE-2019-6130

MuPDF had a SEGV in the function fz_load_page of the fitz/document.c file, as demonstrated by mutool. This was related to page-number mishandling in cbz/mucbz.c, cbz/muimg.c, and svg/svg-doc.c.

CVE-2018-6192

In MuPDF, the pdf_read_new_xref function in pdf/pdf-xref.c allowed remote attackers to cause a denial of service (segmentation violation and application crash) via a crafted PDF file.

For Debian 8 'Jessie', these problems have been fixed in version 1.5-1+deb8u6.

We recommend that you upgrade your mupdf packages.

These security issues were fixed :

  - CVE-2018-6187: Prevent heap-based buffer overflow in the     do_pdf_save_document function. Remote attackers could     leverage the vulnerability to cause a denial of service     via a crafted pdf file (bsc#1077407).

  - CVE-2018-6544: pdf_load_obj_stm could have referenced     the object stream recursively and therefore run out of     error stack, which allowed remote attackers to cause a     denial of service via a crafted PDF document     (bsc#1079100).

  - CVE-2018-6192: The pdf_read_new_xref function allowed     remote attackers to cause a denial of service     (segmentation violation and application crash) via a     crafted pdf file (bsc#1077755).
