Synopsis

The remote Red Hat host is missing one or more security updates for graphite2.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1793 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL graphite2 package based on the guidance in RHSA-2017:1793.
