This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-201201-08
(FontForge: User-assisted execution of arbitrary code)

FontForge is vulnerable to an error when processing the
'CHARSET_REGISTRY' header in font files, which could cause a stack-based
buffer overflow.

Impact :

A remote attacker could entice a user to open a specially crafted BDF
file using FontForge font editor, possibly resulting in the remote
execution of arbitrary code with the privileges of the FontForge process,
or a Denial of Service (application crash).

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=media-gfx/fontforge-20110222-r1'
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 12, 2011. It is likely that your system is
already no longer affected by this issue.
