3. Description:

Graphite2 is a project within SIL's Non-Roman Script Initiative and
Language Software Development groups to provide rendering capabilities for
complex non-Roman writing systems. Graphite can be used to create "smart
fonts" capable of displaying writing systems with various complex
behaviors. With respect to the Text Encoding Model, Graphite handles the
"Rendering" aspect of writing system implementation.

The following packages have been upgraded to a newer upstream version:
graphite2 (1.3.10).

Security Fix(es):

* Various vulnerabilities have been discovered in Graphite2. An attacker
able to trick an unsuspecting user into opening specially crafted font
files in an application using Graphite2 could exploit these flaws to
disclose potentially sensitive memory, cause an application crash, or,
possibly, execute arbitrary code. (CVE-2017-7771, CVE-2017-7772,
CVE-2017-7773, CVE-2017-7774, CVE-2017-7775, CVE-2017-7776, CVE-2017-7777,
CVE-2017-7778)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Holger Fuhrmannek and Tyson Smith as the original
reporters of these issues.
