|
Regenrecht reported multiple vulnerabilities in FreeType via iDefense:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
An integer overflow when parsing values in the Private dictionary table
|
|
in a PFB file, leading to a heap-based buffer overflow
|
|
(CVE-2008-1806).
|
|
</li>
|
|
<li>
|
|
An invalid free() call related to parsing an invalid "number of axes"
|
|
field in a PFB file (CVE-2008-1807).
|
|
</li>
|
|
<li>
|
|
Multiple off-by-one errors when parsing PBF and TTF files, leading to
|
|
heap-based buffer overflows (CVE-2008-1808).
|
|
</li>
|
|
</ul>

|
<impact type="normal">
|
|
<p>
|
|
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.org X server, running as root).
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All FreeType users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/freetype-2.3.6"</code>
|
|
</resolution>
