<p>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.

<description>
|
||
|
<p>Two vulnerabilities have been found in JasPer:</p>
|
||
|
|
||
|
<ul>
|
||
|
<li>The jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c contains
|
||
|
an error that could overwrite certain callback pointers, possibly
|
||
|
causing a heap-based buffer overflow (CVE-2011-4516).
|
||
|
</li>
|
||
|
<li>The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c uses an
|
||
|
incorrect data type, possibly causing a heap-based buffer overflow
|
||
|
(CVE-2011-4517).
|
||
|
</li>
|
||
|
</ul>

<impact type="normal">
|
||
|
<p>A remote attacker could entice a user or automated system to process
|
||
|
specially crafted JPEG-2000 files with an application using JasPer,
|
||
|
possibly resulting in the execution of arbitrary code with the privileges
|
||
|
of the application, or a Denial of Service.

<p>There is no known workaround at this time.</p>

<resolution>

<p>All JasPer users should upgrade to the latest version:</p>
