Synopsis

Multiple vulnerabilities in Blender might result in the remote execution of arbitrary code.

2.  Impact Information

Background

Blender is a 3D creation, animation and publishing program.

Description

Stefan Cornelius (Secunia Research) reported a boundary error within the imb_loadhdr() function in in the file source/blender/imbuf/intern/radiance_hdr.c when processing RGBE images (CVE-2008-1102). Multiple vulnerabilities involving insecure usage of temporary files have also been reported (CVE-2008-1103).

Impact

A remote attacker could entice a user to open a specially crafted file (.hdr or .blend), possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Blender users should upgrade to the latest version:

Code Listing 3.1: Resolution
