Synopsis ========
Insufficient input validation in BlueZ may lead to arbitrary code execution or a Denial of Service.
Background ==========
BlueZ is a set of Bluetooth tools and system daemons for Linux.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-wireless/bluez-utils < 3.36 >=3D 3.36 2 net-wireless/bluez-libs < 3.36 >=3D 3.36 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
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.
Resolution ==========
All bluez-utils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-wireless/bluez-utils-3.36= "
All bluez-libs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-wireless/bluez-libs-3.36"=
