Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Protection mechanism failure
EUVDB-ID: #VU112067
Risk: Low
CVSSv4.0: 6.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2025-32462
CWE-ID:
CWE-693 - Protection Mechanism Failure
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient implementation of security measures when running sudo with -h (--host) option. If the current configuration provides access to users based on the host they are allowed to execute commands, a local user can bypass such a restriction by providing the hostname via the "-h" option they are allowed to execute commands. The vulnerability affects systems that use a common sudoers file that is distributed to multiple machines or when LDAP-based sudoers (including SSSD) is used.
MitigationUpdate the affected package sudo to the latest version.
Vulnerable software versionsUbuntu: 22.04 - 25.04
sudo (Ubuntu package): before 1.9.9-1ubuntu2.5

2) Protection mechanism failure
EUVDB-ID: #VU112066
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2025-32463
CWE-ID:
CWE-693 - Protection Mechanism Failure
