critical Nessus Plugin ID 82292

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated setroubleshoot packages that fix one security issue are now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Important 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.

The setroubleshoot packages provide tools to help diagnose SELinux problems. When Access Vector Cache (AVC) messages are returned, an alert can be generated that provides information about the problem and helps to track its resolution.

It was found that setroubleshoot did not sanitize file names supplied in a shell command look-up for RPMs associated with access violation reports. An attacker could use this flaw to escalate their privileges on the system by supplying a specially crafted file to the underlying shell command. (CVE-2015-1815)

Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for reporting this issue.

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

Solution

Update the affected packages.
