REDHAT-BUG-2278955: Low severity BlueZ BlueZ OBEX Library vulnerability
BlueZ OBEX Library Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that 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 vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20937.
