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.
