Vulnerability from csaf_redhat - Published: 2005-10-11 15:26 - Updated: 2025-11-21 17:29
Summary
Red Hat Security Advisory: libuser security update

Notes

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.
Details
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.
