Summary

Duplicate Advisory: uutils coreutils has an Incorrect Authorization issue

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-47c7-qrm7-mqw7. This link is maintained to preserve external references.

Original Description

The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes rely on the output of id to make security-critical access-control or permission decisions, this discrepancy can lead to unauthorized access or security misconfigurations.

Severity

4.4 (Medium)
