pdf_load_obj_stm in pdf/pdf-xref.c in Artifex MuPDF 1.12.0 could reference the object stream recursively and therefore run out of error stack, which allows remote attackers to cause a denial of service via a crafted PDF document.

The remote host is affected by the vulnerability described in GLSA-201811-15 (MuPDF: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MuPDF. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker, by enticing a user to process a specially crafted       file, could possibly execute arbitrary code, cause a Denial of Service       condition, or have other unspecified impacts.
  Workaround :

    There is no known workaround at this time.

Two vulnerabilities were discovered in MuPDF, a PDF, XPS, and e-book viewer, which may result in denial of service or remote code execution. An attacker can craft a PDF document which, when opened in the victim host, might consume vast amounts of memory, crash the program, or, in some cases, execute code in the context in which the application is running.

CVE-2018-6192 CVE-2018-6544 CVE-2018-1000051 CVE-2018-6187

This update for mupdf fixes several issues.

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).
