Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU47545
Risk: Medium
CVSSv3.1: 7.9 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-12351
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input within the BlueZ implementation in Linux kernel. A remote attacker on the local network can pass specially crafted input to the application and execute arbitrary code on the system.
MitigationUpdate the affected package linux-hardened to version 5.8.16.a-1.
Vulnerable software versionsArch Linux: All versions

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
EUVDB-ID: #VU47546
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-12352
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper access restrictions in BlueZ implementation in Linux kernel. A remote attacker on the local network can pass specially crafted input to the application and gain access to sensitive information.
MitigationUpdate the affected package linux-hardened to version 5.8.16.a-1.

EUVDB-ID: #VU47549
Risk: Medium
CVSSv3.1: 6.4 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-24490
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within BlueZ implementation in Linux kernel. A remote attacker on the local network can pass specially crated data to the system and perform a denial of service (DoS) attack.
Update the affected package linux-hardened to version 5.8.16.a-1.
