The JasPer Project is an open-source initiative to provide a free
|
|
software-based reference implementation of the codec specified in the
|
|
JPEG-2000 Part-1 (jpeg2k) standard.

<p>
|
|
Marc Espie and Christian Weisgerber have discovered multiple
|
|
vulnerabilities in JasPer:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Multiple integer overflows might allow for insufficient memory
|
|
allocation, leading to heap-based buffer overflows (CVE-2008-3520).
|
|
</li>
|
|
<li>
|
|
The jas_stream_printf() function in libjasper/base/jas_stream.c uses
|
|
vsprintf() to write user-provided data to a static to a buffer, leading
|
|
to an overflow (CVE-2008-3522).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
Remote attackers could entice a user or automated system to process
|
|
specially crafted jpeg2k files with an application using JasPer,
|
|
possibly leading to the execution of arbitrary code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All JasPer users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r3"</code>
