Name of the Vulnerable Software and Affected Versions BlueZ (affected versions not specified)

Description This issue allows network-adjacent attackers to disclose sensitive information on affected installations of BlueZ. User interaction is required to exploit this issue, as the target must connect to a malicious Bluetooth device. The specific flaw exists within the handling of OBEX protocol parameters. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other issues to execute arbitrary code in the context of root.

Recommendations At the moment, there is no information about a newer version that contains a fix for this issue.
