IMHO, you have misinterpreted the advisories.

http://secunia.com/advisories/13232/[1] refers to the first part of the advisory (note the [1]), which is a true remote exploit:

"Stefan Esser has reported multiple vulnerabilities within the smb filesystem (smbfs) implementation that are caused due to various types of errors when handling server responses.

Successful exploitation requires that a malicious person has control over a smb server or is able to intercept and manipulate traffic."

The "local users" refers to the second part of the advisory (the unix_dgram_recvmsg() issue). For some reason, Secunia's summary blurb only describes the second part. Go figure.

http://secunia.com/advisories/14713/[2]

"A signedness error in the "bluez_sock_create()" function when creating bluetooth sockets can potentially be exploited to gain root privileges on a vulnerable system."

If I'm reading this right, a malicious user can take over a server by crafting malicious bluetooth packets, in other words, that's a remote root. (Remember, bluetooth devices can be very long-range: http://www.smallnetbuilder.com/content/view/24256/98/)

A second remote hole for OpenBSD

Because OpenBSD ships with neither SMBFS nor Bluetooth enabled by default, these remote holes would not count against it. Therefore, they should not count against Linux. As ajross was saying, you need to compare apples to apples.

Personally, I think pretty much any measurement against OpenBSD's default install is meaningless. Nobody runs it! "Only 12 remote holes in a fully-provisioned OpenBSD LAMP setup!" would be a much better statistic.
