lib3ds: User-assisted execution of arbitrary code

Background

lib3ds is a library for managing 3D-Studio Release 3 and 4 .3DS files.

Description

An array index error has been discovered in lib3ds.

Impact

A remote attacker could entice a user to open a specially crafted 3DS file using an application linked against lib3ds, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All lib3ds 2.0 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/lib3ds-2.0.0_rc1"

All lib3ds 1.3 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/lib3ds-1.3.0-r1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
