<br></dd>
<br><dt>More information:</dt>
<dd>A heap-based buffer overflow vulnerability was discovered by Damian Put in <br>
Blender BlenLoader 2.0 through 2.40pre which allows remote attackers to cause a <br>
denial of service (application crash) and possibly execute arbitrary code via a <br>
.blend file with a negative bhead.len value, which causes less memory to be <br>
allocated than expected, possibly due to an integer overflow. <br>
<br>
Please note, this issue has already been fixed in stable in security <br>
announcement DSA-1039-1 <br>
</dd>
<br><dt>For the testing distribution (etch) this is fixed in version 2.37a-1.1etch1</dt>
<dt>For the unstable distribution (sid) this is fixed in version 2.40-1</dt>
<br><dt>This upgrade is recommended if you use Blender.<dt>
<br><dt>If you have the secure testing lines in your sources.list, you can update by running this command as root:</dt>
<dd>apt-get update && apt-get install blender</dd>
<br>
<br>
<dt>To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:<dt>
