Synopsis :

The remote openSUSE host is missing a security update.

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).
