http://secunia.com/advisories/13541/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
Mesh Viewer 0.x
http://secunia.com/product/4418/

DESCRIPTION:
Mohammed Khan and Danny Lungstrom have reported a vulnerability in
Mesh Viewer, which can be exploited by malicious people to compromise
a user's system.

The vulnerability is caused due to a boundary error in the
"Mesh::type()" function when processing mesh files. This can be
exploited to cause a buffer overflow by tricking a user into viewing
a specially crafted mesh file.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in version 0.2.2. Other versions
may also be affected.

SOLUTION:
Don't view untrusted mesh files.

Use another product.
