Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |

| 19 |
execution or a Denial of Service. |

|
| 21 |
Background |
| 22 |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
It has been reported that the Bluetooth packet parser does not validate |
| 42 |
string length fields in SDP packets. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A physically proximate attacker using a Bluetooth device with an |
| 48 |
already established trust relationship could send specially crafted |
| 49 |
requests, possibly leading to arbitrary code execution or a crash. |
| 50 |
Exploitation may also be triggered by a local attacker registering a |
| 51 |
service record via a UNIX socket or D-Bus interface. |
| 52 |
|
| 53 |
Workaround |
| 54 |
========== |
| 55 |
|
| 56 |
There is no known workaround at this time. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All bluez-utils users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=net-wireless/bluez-utils-3.36" |
| 65 |
|
| 66 |
