Nine months after the notification of Blueborne researchers bug, Lenovo released a patch for 3's popular Android tablet series.
Lenovo, the third-largest tablet maker in the world, said the patches are available for download via its site, and are available for 4 Lenovo Tab, 14 Tab essential and 3 Yoga tab.
"The upgrades must be implemented immediately," Lenovo said in its release notes, as the vulnerabilities posed by BlueBorne are critical and of high priority.
"We finished the upgrades for our laptops some time ago, and with this release, the BlueBorne Cycle closes completely." The company said it was not common to delay security patches so much, and added that there is a reason that some models are upgraded while others are not.
In September of 2017 along with the discovery of BlueBorne, the vulnerabilities it caused to billions of devices on Android and Apple devices were announced. It related smartphones, tablets, printers, smart TVs and IoT devices that used the Bluetooth protocol. Vulnerabilities allowed the attacker to take full control of a device, share malware, or perform a man in the middle attack to access critical data.
At that time, it is estimated that 5.3 billions of devices were exposed to this type of attack, with 2.1 billions of them being Android devices. Only 900.000 from them had software updates available at short notice to correct the vulnerability.
The list of tablets for which Lenovo released updates is as follows: TB3-X70F, TB3-X70I, TB3-X70L, TB3-X70N, TB-7304F, TB-7304I, TB-7304X, 7504X TB-7504V, TB-8704X, TB-X8704F, TB-X304L, TB-X304N, TB-X304A, TB-X704F, TB-X704L, TB-X704V, YT-X704F, YT-X703L and YT-X703X.
