-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4647-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso March 26, 2020 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : bluez CVE ID : CVE-2020-0556 Debian Bug : 953770 It was reported that the BlueZ's HID and HOGP profile implementations don't specifically require bonding between the device and the host. Malicious devices can take advantage of this flaw to connect to a target host and impersonate an existing HID device without security or to cause an SDP or GATT service discovery to take place which would allow HID reports to be injected to the input subsystem from a non-bonded source. For the HID profile an new configuration option (ClassicBondedOnly) is introduced to make sure that input connections only come from bonded device connections. The options defaults to 'false' to maximize device compatibility. For the oldstable distribution (stretch), this problem has been fixed in version 5.43-2+deb9u2. For the stable distribution (buster), this problem has been fixed in version 5.50-1.2~deb10u1. We recommend that you upgrade your bluez packages. For the detailed security status of bluez please refer to its security tracker page at: https://security-tracker.debian.org/tracker/bluez Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAl59Lf9fFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0QYMA/+JBxFU7rzhzE+cQMnw0zhQ7v5eJg6Xmqxc7oCOgrbjCSfOS7f6FkieJxs crx6lG8g8TJAT3p+3UB/V7K7qZ7eR4WyebuFO9Zhzw++/Lta/WHYG/HJeLaLziBC G9PewvpioBZep60t/GtS9hJ322XFMVmi05rq9jfEVmAtkGXQ2YFcZm6EIevI/C4j EwmAFMszh2jCozevWo5//pgy5aVNKWoWZNjK836sIb8m3xkmRLkM55vwU05qGYFp p5tz9Weqt6gFbSzRkVfuiqz2duYltdquw38O3kgpqci5stKNw3z2SQMnhj4n1JcB yM9gdlK651eGEvZ9j402dbXtyr18cQ0svsZDwoKQ1B61nsZtyS026Ecj/c4HluBF LbBH/kE/oQW7kU2yfDcWdKH8ISZSL0d/JpfUl0qXvpNx33ApjSiNMsOzf0/b8SKc WsYpsdS5WYq8wgG8Orhaa51cw8zoCNZRdx58njYyxWGMszDa9LbZk+Hgr4fad96y wUo3rGNxz6EC26ewUtSPToXXnGmRLhp1rg40zvNMNE42KenlkR5kipn203OSxuw4 g+CHJ2whA5YM9Dr6z1NF1udDGAqdq+TeI/uY4WY/JT6NbawZ+ziFGcKetATYiwIL wAdYopw3DleEPGSEifbavriVqWBv0biTy9oVR/YeltiEE9UjNpY= =odxF -----END PGP SIGNATURE-----
