GLSA-200806-10 : FreeType: User-assisted execution of arbitrary code

This script is Copyright (C) 2008-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200806-10
(FreeType: User-assisted execution of arbitrary code)

Regenrecht reported multiple vulnerabilities in FreeType via iDefense:
An integer overflow when parsing values in the Private dictionary table
in a PFB file, leading to a heap-based buffer overflow
An invalid free() call related to parsing an invalid 'number of axes'
field in a PFB file (CVE-2008-1807).
Multiple off-by-one errors when parsing PBF and TTF files, leading to
heap-based buffer overflows (CVE-2008-1808).

Impact :

A remote attacker could entice a user to open a specially crafted TTF
or PBF file, possibly resulting in the execution of arbitrary code with
the privileges of the user running an application linked against
FreeType (such as the X server, running as root).

Workaround :

There is no known workaround at this time.

Solution :

All FreeType users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/freetype-2.3.6'

Risk factor :

High / CVSS Base Score : 7.5
