Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Off-by-one

EUVDB-ID: #VU87448

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-1441

CWE-ID: CWE-193 - Off-by-one Error

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to an off-by-one error in the udevListInterfacesByStatus() function when the number of interfaces exceeds the size of the "names" array. A local user can trigger an off-by-one error and crash the daemon.

Mitigation

Install updates from vendor's repository.
