Description Nico Baggus 2017-09-12 18:53:16 UTC
Bluetooth stacks have various security flaws, Linux as well as Android as well as IOS as well as other devices.



Reproducible: Always

Actual Results:  
This isn't mentioned in a GLSA also not found in BZ.

Thank you for the report, from URL:

All versions of the SDP server in BlueZ 5.46 and earlier are vulnerable to an information disclosure vulnerability which allows remote attackers to obtain sensitive information from the bluetoothd process memory. This vulnerability lies in the processing of SDP search attribute requests.

From the 8 vulnerabilities, 2 of them involve Linux environments and one is kernel related, we treat kernel vulnerabilities in a different manner.

What does this mean exactly?
How is this issue being addressed?
A fix has already been committed to the kernel https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e860d2c904d1a9f38a24eb44c9f34b8f915a6ea3

I'm unsure if there are also fixes needed for bluez

Yes, there is also a patch for Bluez:

Hi @Simon, 

Kernel vulnerabilities are addressed under "kernel" label, which is handled by the kernel-security team, bug 630840 was already filled before this one.

BlueBorne is a group of vulnerabilities that affect multiple devices, some of them include Android, Windows, and iPhone, those vulnerabilities are out of the scope from the Gentoo-security team, and most likely won't affect our systems.

On the other hand, as you can see, we already have the new version from bluez in portage (thanks to Pacho), we'll test it before to ensure that is safe and then release the GLSA once both issues are fixed.

Hope this is clearer,
