Oracle Linux 7 : libuser (ELSA-2015-1483)

High Nessus Plugin ID 84975


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2015:1483 :

Updated libuser packages that fix two security issues are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

Two flaws were found in the way the libuser library handled the /etc/passwd file. A local attacker could use an application compiled against libuser (for example, userhelper) to manipulate the /etc/passwd file, which could result in a denial of service or possibly allow the attacker to escalate their privileges to root.
(CVE-2015-3245, CVE-2015-3246)

Red Hat would like to thank Qualys for reporting these issues.

All libuser users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.


Update the affected libuser packages.
