Synopsis:	Moderate: libuser security update
Issue date:	2011-01-20
CVE Names:	CVE-2011-0002

It was discovered that libuser did not set the password entry correctly
when creating LDAP (Lightweight Directory Access Protocol) users. If an
administrator did not assign a password to an LDAP based user account,
either at account creation with luseradd, or with lpasswd after account
creation, an attacker could use this flaw to log into that account with
a default password string that should have been rejected. (CVE-2011-0002)

Note: LDAP administrators that have used libuser tools to add users
should check existing user accounts for plain text passwords, and reset
them as necessary.
