RHSA-2005:770 - Security Advisory

Topic

Updated libuser packages that fix various security issues are now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

The libuser library implements a standardized interface for manipulating
and administering user and group accounts. The library uses pluggable
back-ends to interface to its data sources. Sample applications that are
modeled after applications from the shadow password suite are included in
the package.

Several denial of service bugs were discovered in libuser. Under certain
conditions it is possible for an application linked against libuser to
crash or operate irregularly. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-2392 to these issues.

All users of libuser are advised to upgrade to these updated packages,
which contain a backported fix and are not vulnerable to these issues.
