EulerOS 2.0 SP3 : bluez (EulerOS-SA-2022-1707)

critical Nessus Plugin ID 161589

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the bluez packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- An issue was discovered in bluetoothd in BlueZ through 5.48. The vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data. The root cause can be found in the function service_attr_req of sdpd-request.c. The server does not check whether the CSTATE data is the same in consecutive requests, and instead simply trusts that it is the same. (CVE-2019-8921)

- A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48. There isn't any check on whether there is enough space in the destination buffer. The function simply appends all data passed to it. The values of all attributes that are requested are appended to the output buffer. There are no size checks whatsoever, resulting in a simple heap overflow if one can craft a request where the response is large enough to overflow the preallocated buffer. This issue exists in service_attr_req gets called by process_request (in sdpd-request.c), which also allocates the response buffer. (CVE-2019-8922)

- An issue was discovered in gatt-database.c in BlueZ 5.61. A use-after-free can occur when a client disconnects during D-Bus processing of a WriteValue call. (CVE-2021-43400)

- A heap overflow vulnerability was found in bluez in versions prior to 5.63. An attacker with local network access could pass specially crafted files causing an application to halt or crash, leading to a denial of service. (CVE-2022-0204)

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.

Solution

Update the affected bluez packages.
