According to the version of the bluez package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - In BlueZ before 5.55, a double free was found in the     gatttool disconnect_cb() routine from shared/att.c. A     remote attacker could potentially cause a denial of     service or code execution, during service discovery,     due to a redundant disconnect MGMT     event.(CVE-2020-27153)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for bluez fixes the following issues :

  - CVE-2020-27153: Fixed possible crash on disconnect     (bsc#1177895).

    Jay LV discovered that BlueZ incorrectly handled redundant disconnect MGMT events. A local attacker could     use this issue to cause BlueZ to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-27153)

    Ziming Zhang discovered that BlueZ incorrectly handled certain array indexes. A local attacker could use     this issue to cause BlueZ to crash, resulting in a denial of service, or possibly obtain sensitive     information. This issue only affected Ubuntu 20.04 LTS and Ubuntu 20.10. (CVE-2021-3588)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that there was a double-free vulnerability in bluez, a suite of Bluetooth tools, utilities and daemons.

For Debian 9 'Stretch', this problem has been fixed in version 5.43-2+deb9u3.

We recommend that you upgrade your bluez packages.
