   An update that fixes three vulnerabilities is now available.

Description:

   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).
