Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Insufficient input validation in BlueZ may lead to arbitrary code
execution or a Denial of Service.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
BlueZ is a set of Bluetooth tools and system daemons for Linux.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
It has been reported that the Bluetooth packet parser does not validate
string length fields in SDP packets.
Impact
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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"=
