Debian Security Advisory DSA-4951-1 [email protected]

Package : bluez
CVE ID : CVE-2020-26558 CVE-2020-27153 CVE-2021-0129
Debian Bug : 989614
Several vulnerabilities were discovered in Bluez, the Linux Bluetooth
protocol stack.
CVE-2020-26558 / CVE-2021-0129
It was discovered that Bluez does not properly check permissions
during pairing operation, which could allow an attacker to
impersonate the initiating device.
CVE-2020-27153
Jay LV discovered a double free flaw in the disconnect_cb() routine
in the gattool. A remote attacker can take advantage of this flaw
during service discovery for denial of service, or potentially,
execution of arbitrary code.
For the stable distribution (buster), these problems have been fixed in
version 5.50-1.2~deb10u2.
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
