Test ID:1.3.6.1.4.1.25623.1.0.69181
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:0170
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2011:0170.

The libuser library implements a standardized interface for manipulating
and administering user and group accounts. Sample applications that are
modeled after applications from the shadow password suite (shadow-utils)
are included in these packages.

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.

Users of libuser should upgrade to these updated packages, which contain a
backported patch to correct this issue.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
