Debian Security Advisory DSA-1567-1 security@debian.org

Package : blender
Vulnerability : buffer overrun
Problem type : local (remote)
Debian-specific: no
CVE Id(s) : CVE-2008-1102

Stefan Cornelius discovered a vulnerability in the Radiance High
Dynamic Range (HDR) image parser in Blender, a 3D modelling
application. The weakness could enable a stack-based buffer overflow
and the execution of arbitrary code if a maliciously-crafted HDR file
is opened, or if a directory containing such a file is browsed via
Blender's image-open dialog.

For the stable distribution (etch), these problems have been fixed in
version 2.42a-7.1+etch1.

For the unstable distribution (sid), these problems have been fixed in
version 2.45-5.

We recommend that you upgrade your blender packages.
