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).
