EulerOS 2.0 SP5 : bluez (EulerOS-SA-2022-1263)

high Nessus Plugin ID 170504

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - 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)

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.
