Published: 2016-06-24 03:26:43
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:C/A:C

Detection Type:
Linux Distribution Package

Summary:
Check the version of setroubleshoot

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The setroubleshoot Linux Distribution 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 Linux Distribution 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) The CVE-2016-4444 and CVE-2016-4446 issues were discovered by Milos Malik (Red Hat) and the CVE-2016-4989 issue was discovered by Red Hat Product Security. Note: On Red Hat Enterprise Linux 7.0 and 7.1, the setroubleshoot is run with root privileges. Therefore, these issues could allow an attacker to execute arbitrary code with root privileges.

Affected Versions:
setroubleshoot on CentOS 7

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
