4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \\n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \\r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that \"cat /etc/passwd\" shows a rogue user account.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Micro 5.5:login_defs-4.8.1-150500.3.3.1.noarch","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.aarch64","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.ppc64le","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.s390x","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2023-29383","url":"https://www.suse.com/security/cve/CVE-2023-29383"},{"category":"external","summary":"SUSE Bug 1210507 for CVE-2023-29383","url":"https://bugzilla.suse.com/1210507"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Micro 5.5:login_defs-4.8.1-150500.3.3.1.noarch","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.aarch64","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.ppc64le","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.s390x","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":5.5,"baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Micro 5.5:login_defs-4.8.1-150500.3.3.1.noarch","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.aarch64","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.ppc64le","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.s390x","SUSE Linux Enterprise Micro 5.5:shadow-4.8.1-150500.3.3.1.x86_64"]}],"threats":[{"category":"impact","date":"2024-03-27T09:51:45Z","details":"moderate"}],"title":"CVE-2023-29383"},{"cve":"CVE-2023-4641","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2023-4641"}],"notes":[{"category":"general","text":"A flaw was found in shadow-utils.
