A vulnerability in BlueZ might allow remote attackers to execute arbitrary code.
| Package | net-wireless/bluez on all architectures |
|---|---|
| Affected versions | < 5.55 |
| Unaffected versions | >= 5.55 |
Set of tools to manage Bluetooth devices for Linux.
It was discovered that there was a double-free vulnerability in Bluez after the service discovery which occurs after a Bluetoth Low Energy (BLE) connection has been established to a device.
A remote attacker, by enticing a user to connect to a malicious GATT server or device, could cause the execution of arbitrary code with the privileges of the user running gatttool client or cause a Denial of Service condition.
There is no known workaround at this time.
All BlueZ users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-wireless/bluez-5.55"
