<description>
|
|
<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).

|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All FontForge users should upgrade to the latest version:</p>
|

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/fontforge-20110222-r1"
|
|
</code>
