Description SMASH SMASH 2023-12-22 08:47:52 UTC 
VULNERABILITY DETAILS 	

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.

ADDITIONAL DETAILS 	

-- Mitigation: Given the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the application.
