Dist Redhat Esm H88
Newly released setroubleshoot updates resolve a significant vulnerability affecting Red Hat Enterprise Linux—urgent attention needed for user protection.
Updated setroubleshoot packages that fix one security issue are now available for Red Hat Enterprise Linux 5, 6, and 7

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

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.
