Please note, this issue has already been fixed in stable and unstable in security announcement DSA-1039-1 For the testing distribution (etch) this is fixed in version 2.37a-1.1etch1 For the unstable distribution (sid) has already been fixed in version 2.40-1 This upgrade is recommended if you use Blender. The Debian testing security team does not track security issues for the stable (sarge) and oldstable (woody) distributions.
