Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Out-of-bounds read
EUVDB-ID: #VU8442
Risk: Low
CVSSv4.0: 5.7 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2017-1000250
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: Yes
DescriptionThe vulnerability allows an adjacent attacker to obtain potentially sensitive information on the target system.
The weakness exists in the bluetoothd implementation of the Service Discovery Protocol (SDP) due to out-of-bounds heap read condition in the service_search_attr_req function. An adjacent attacker send specially crafted requests that has Bluetooth enabled in the SDP server and access sensitive information, such as encryption keys, from bluetoothd process memory.
Successful exploitation of the vulnerability results in information disclosure.
