Gentoo Linux Security Advisory

Title: Blender: Multiple vulnerabilities (GLSA 200805-12)
Severity: normal
Exploitable: remote
Date: May 12, 2008
Bug(s): #219008
ID: 200805-12

Synopsis

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

Background

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

Affected Packages

Package: media-gfx/blender
Vulnerable: < 2.43-r2
Unaffected: >= 2.43-r2
Architectures: All supported architectures


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.

Workaround

There is no known workaround at this time.

Resolution

All Blender users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/blender-2.43-r2"
