Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities in Blender might result in the remote |
| 22 |
execution of arbitrary code. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Blender is a 3D creation, animation and publishing program. |
| 28 |
|
| 29 |
Affected packages |
| 30 |
================= |
| 31 |
|
| 32 |
------------------------------------------------------------------- |
| 33 |
Package / Vulnerable / Unaffected |
| 34 |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Stefan Cornelius (Secunia Research) reported a boundary error within |
| 41 |
the imb_loadhdr() function in in the file |
| 42 |
source/blender/imbuf/intern/radiance_hdr.c when processing RGBE images |
| 43 |
(CVE-2008-1102). Multiple vulnerabilities involving insecure usage of |
| 44 |
temporary files have also been reported (CVE-2008-1103). |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
A remote attacker could entice a user to open a specially crafted file |
| 50 |
(.hdr or .blend), possibly resulting in the remote execution of |
| 51 |
arbitrary code with the privileges of the user running the application. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All Blender users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=media-gfx/blender-2.43-r2" |
| 65 |
|
