NetBSD Security Note 20061214-1
Topic: Kernel memory leakage in firewire interface
A kernel memory disclosure bug has been found in the NetBSD firewire
This issue has been assigned CVE-2006-6013.
On the 15th of November 2006 a posting was made to a public list
which detailed a "NetBSD all versions FireWire IOCTL kernel integer
overflow information disclousure."
The advisory listed "NetBSD all versions" as being affected. Upon
further investigation this was found not to be the case and there
are a number of other details that should be taken into account
when trying to assess this issue:
* This issue impacts NetBSD-current before November 16 2006. If
you are running NetBSD-current sources after this date you have the
fix included in the kernel.
* This issue impacts the NetBSD-4 branch before December 3, 2006.
NetBSD 4.0_BETA2 contains the fix.
* No current NetBSD releases are impacted e.g. NetBSD 2* and NetBSD 3*.
* Although a complete list is not currently available we do not
believe that all architectures are impacted by this bug.
* The fw nodes are not created by default in /dev in a NetBSD
* When the fw* nodes are created using MAKEDEV, they are created with mode
660 and ownership is set to root:operator.
We recommend that all users of NetBSD-current upgrade their sources
to after November 16 2006. In addition to this all users of NetBSD-4
should update to sources after December 3 2006.
