Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Predictable from Observable State
EUVDB-ID: #VU52596
Risk: Low
CVSSv4.0: 1.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-13529
CWE-ID:
CWE-341 - Predictable from Observable State
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to reconfigure the target device.
The vulnerability exists due to usage of predictable Transactions Identifiers when processing DHCP ACK packets. A remote attacker on the same network can forge the FORCERENEW and DHCP ACK packets to reconfigure the systemd’s DHCP client settings.
Install updates from vendor's repository.
