<p>FontForge is a PostScript font editor and converter.</p>
<p>FontForge is vulnerable to an error when processing the
"CHARSET_REGISTRY" header in font files, which could cause a stack-based
buffer overflow.
<impact type="normal">
<p>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).
<p>There is no known workaround at this time.</p>
<p>All FontForge users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=media-gfx/fontforge-20110222-r1"
<p>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.
