EulerOS 2.0 SP1 : setroubleshoot
Medium Nessus Plugin ID 99796
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording 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.
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected setroubleshoot setroubleshoot-plugins packages.
