Several vulnerabilities have been discovered in blender, a very fast and versatile 3D modeller/renderer. The Common Vulnerabilities and Exposures Project identifies the following problems:
Joxean Koret discovered that due to missing input validation a provided script is vulnerable to arbitrary command execution.
Damian Put discovered a buffer overflow that allows remote attackers to cause a denial of service and possibly execute arbitrary code.
The old stable distribution (woody) is not affected by this problem.
For the stable distribution (sarge) this problem has been fixed in version 2.36-1sarge1.
For the unstable distribution (sid) this problem has been fixed in version 2.40-1.
We recommend that you upgrade your blender package.
