CVE-2024-56433
Description
A flaw was found in shadow-utils. Affected versions of shadow-utils establish a default /etc/subuid behavior, for example, uid 100000 through 165535 for the first user account, that can conflict with the uids of users defined on locally administered networks. This issue potentially leads to account takeover by leveraging newuidmap for access to an NFS home directory or same-host resources for remote logins by these local network users.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
