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

Description

The 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. 

Mitigation

Install updates from vendor's repository.

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

Exploit availability: Yes

Description

The 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 -R (--chroot) option. A local user can run arbitrary commands as root, even if they are not listed in the sudoers file.

Note, the vulnerability affects installations with Name Service Switch (NSS) enabled. 

Mitigation

Install updates from vendor's repository.
