Shadow Utils useradd utility sets incorrect file permissions

Vulnerability Note VU#312692

Original Release Date: 2007-12-14 | Last Revised: 2007-12-14

Overview

The Shadow Utilities contain a vulnerability that may result in new user mailboxes having arbitrary permissions.

Description

The Shadow Utilities provide tools to manage user accounts.

When a new mailbox is created using the useradd utility, the open() function does not receive the expected arguments while O_CREAT is present. The result of this error is that random permissions are applied to the new mailbox.

Impact

A local, unprivileged attacker may be able to gain access to newly created mailbox files.

Solution

Affected vendors have released updates to address this issue. Users are encouraged to see the Systems Affected portion of this document for a partial list of affected vendors.

Openwall GNU/*/Linux (Owl) is not affected. We had fixed this issue while introducing this functionality into Owl in November, 2001.
