Ubuntu Security Notice USN-699-1          December 22, 2008
blender vulnerabilities
CVE-2008-1102, CVE-2008-4863
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  blender                         2.41-1ubuntu4.1

After a standard system upgrade you need to restart Blender to effect
the necessary changes.

Details follow:

It was discovered that Blender did not correctly handle certain malformed
Radiance RGBE images. If a user were tricked into opening a .blend file
containing a specially crafted Radiance RGBE image, an attacker could execute
arbitrary code with the user's privileges. (CVE-2008-1102)

It was discovered that Blender did not properly sanitize the Python search
path. A local attacker could execute arbitrary code by inserting a specially
crafted Python file in the Blender working directory. (CVE-2008-4863)


Updated packages for Ubuntu 6.06 LTS:
