"This update for cairo fixes the following issues :

  - CVE-2016-9082: Fixed a segfault when using >4GB images
    since int values were used for pointer operations
    (bsc#1007255).

  - CVE-2017-9814: Replace malloc with _cairo_malloc and
    check cmap size before allocating to prevent DoS
    (bsc#1049092).

  - CVE-2017-7475: Fix a segfault in get_bitmap_surface due
    to malformed font (bsc#1036789).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
