Summary

Insecure Preservation of SUID/SGID Bits during ZIP Extraction Leading to Potential Privilege Escalation

Details

The zip crate preserves privileged Unix permission bits (SUID, SGID, and sticky bits) from ZIP external_attributes during extraction, instead of masking them to safe permission bits. If a privileged process (for example, root in an installer, CI/CD pipeline, or container build) extracts an attacker-controlled ZIP archive using ZipArchive::extract() or the stream extraction API, files can be created as setuid-root or setgid. This behavior allows the creation of SUID/SGID files during extraction, which can lead to local privilege escalation depending on the execution environment.
