RHSA-2011:0930 - Moderate: NetworkManager security update
Synopsis
Moderate: NetworkManager security update
Type/Severity
Security Advisory Moderate
Topic
Updated NetworkManager packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Description
NetworkManager is a network link manager that attempts to keep a wired or wireless network connection active at all times.
It was found that NetworkManager did not properly enforce PolicyKit settings controlling the permissions to configure wireless network sharing. A local, unprivileged user could use this flaw to bypass intended PolicyKit restrictions, allowing them to enable wireless network sharing. (CVE-2011-2176)
Users of NetworkManager should upgrade to these updated packages, which contain a backported patch to correct this issue. Running instances of NetworkManager must be restarted ("service NetworkManager restart") for this update to take effect.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
