Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU84667

Risk: Medium

CVSSv4.0: 4.4 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-51596

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when handling the Phone Book Access profile. A remote attacker can trick the victim into connection to a malicious Bluetooth device, trigger a heap-based buffer overflow and execute arbitrary code on the system.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 42

libell: before 0.74-1.fc42

iwd: before 3.4-1.fc42

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Out-of-bounds read

EUVDB-ID: #VU84668

Risk: Low

CVSSv4.0: 0.4 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-51594

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling OBEX protocol parameter. A remote attacker can trick the victim into connecting to a malicious device, trigger an out-of-bounds read and gain access to sensitive information.

Mitigation

Install updates from vendor's repository.
