USN-256-1: bluez-hcidump vulnerability
Posted on: 02/21/2006 05:52 PM

A new bluez-hcidump vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-256-1 February 21, 2006
bluez-hcidump vulnerability
CVE-2006-0670
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

bluez-hcidump

The problem can be corrected by upgrading the affected package to
version 1.5-2ubuntu0.1 (for Ubuntu 4.10), 1.12-1ubuntu0.1 (for Ubuntu
5.04), or 1.23-0ubuntu1.1 (for Ubuntu 5.10). In general, a standard
system upgrade is sufficient to effect the necessary changes.

Details follow:

Pierre Betouin discovered a Denial of Service vulnerability in the
handling of the L2CAP (Logical Link Control and Adaptation Layer
Protocol) layer. By sending a specially crafted L2CAP packet through a
wireless Bluetooth connection, a remote attacker could crash hcidump.

Since hcidump is mainly a debugging tool, the impact of this flaw is
very low.
