<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.

<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>

<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.
