src/sdp.c in bluez-libs 3.30 in BlueZ, and other bluez-libs before 3.34 and bluez-utils before 3.34 versions, does not validate string length fields in SDP packets, which allows remote SDP servers to cause a denial of service or possibly have unspecified other impact via a crafted length field that triggers excessive memory allocation or a buffer over-read.

From Red Hat Security Advisory 2008:0581 :

Updated bluez-libs and bluez-utils packages that fix a security flaw are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The bluez-libs package contains libraries for use in Bluetooth applications. The bluez-utils package contains Bluetooth daemons and utilities.

An input validation flaw was found in the Bluetooth Session Description Protocol (SDP) packet parser used by the Bluez Bluetooth utilities. A Bluetooth device with an already-established trust relationship, or a local user registering a service record via a UNIX(r) socket or D-Bus interface, could cause a crash, or possibly execute arbitrary code with privileges of the hcid daemon.
(CVE-2008-2374)

Users of bluez-libs and bluez-utils are advised to upgrade to these updated packages, which contains a backported patch to correct this issue.

Users of bluez-libs and bluez-utils are advised to upgrade to these updated packages, which contains a backported patch to correct this issue.

Missing length checks in bluez-libs could cause a buffer overflow in Bluetooth applications. Malicious bluetooth devices could potentially exploit that to execute arbitrary code (CVE-2008-2374).

Note: The source code of each application that uses vulnerable functions of bluez-libs needs to be adapted to actually fix the problem.

An input validation flaw was found in the Bluetooth Session Description Protocol (SDP) packet parser used in the Bluez bluetooth utilities. A bluetooth device with an already-trusted relationship, or a local user registering a service record via a UNIX socket or D-Bus interface, could cause a crash and potentially execute arbitrary code with the privileges of the hcid daemon (CVE-2008-2374).

The updated packages have been patched to correct this issue.

The remote host is affected by the vulnerability described in GLSA-200903-29 (BlueZ: Arbitrary code execution)

    It has been reported that the Bluetooth packet parser does not validate     string length fields in SDP packets.
  Impact :

    A physically proximate attacker using a Bluetooth device with an     already established trust relationship could send specially crafted     requests, possibly leading to arbitrary code execution or a crash.
    Exploitation may also be triggered by a local attacker registering a     service record via a UNIX socket or D-Bus interface.
  Workaround :

    There is no known workaround at this time.

The remote Fedora host is missing one or more security updates :
