Name of the Vulnerable Software and Affected Versions
bluez versions prior to 5.63
Description
A heap overflow vulnerability was found in the implementation of the GATT protocol stack for Linux BlueZ. This issue is related to a buffer overflow. An attacker with local network access could pass specially crafted files, causing an application to halt or crash, leading to a denial of service. The exploitation of this vulnerability may also allow a remote attacker to execute arbitrary code by sending specially crafted files.
Recommendations
For versions prior to 5.63, update to version 5.63 or later to resolve the issue. As a temporary workaround, consider restricting access to the Bluetooth functionality to minimize the risk of exploitation.
