EulerOS 2.0 SP1 : setroubleshoot setroubleshoot-plugins (EulerOS-SA-2016-1033)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the setroubleshoot
setroubleshoot-plugins packages installed, the EulerOS installation
on the remote host is affected by the following vulnerabilities :

- 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.

- The setroubleshoot-plugins package provides a set of
analysis plugins for use with setroubleshoot. Each
plugin has the capacity to analyze SELinux AVC data and
system data to provide user friendly reports describing
how to interpret SELinux AVC denials.

- Security Fix(es):

- Shell command injection flaws were found in the way the
setroubleshoot executed external commands. A local
attacker able to trigger certain SELinux denials could
use these flaws to execute arbitrary code with
privileges of the setroubleshoot user.(CVE-2016-4989)

- Shell command injection flaws were found in the way the
setroubleshoot allow_execmod and allow_execstack
plugins executed external commands. A local attacker
able to trigger an execmod or execstack SELinux denial
could use these flaws to execute arbitrary code with
privileges of the setroubleshoot user.
(CVE-2016-4444,CVE-2016-4446)
