SB2025061967 - SUSE update for systemd

Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Improper Privilege Management (CVE-ID: CVE-2022-4415)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to improper privilege management when handling coredumps in coredump/coredump.c. A local user can gain access to sensitive information.

The vulnerability affects systems with libacl support.

2) Improper Privilege Management (CVE-ID: CVE-2023-26604)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper privilege management for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.

3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2025-4598)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists in systemd-coredump when handling process crashes. A local user who can force a SUID process to crash can replace it with a non-SUID binary to access the original's privileged process coredump and read sensitive data, such as /etc/shadow content, loaded by the original process.

Remediation

Install update from vendor's website.
