-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: setroubleshoot and setroubleshoot-plugins security update Advisory ID: RHSA-2016:1293-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1293 Issue date: 2016-06-23 CVE Names: CVE-2016-4444 CVE-2016-4446 CVE-2016-4989 ===================================================================== 1. Summary: An update for setroubleshoot and setroubleshoot-plugins is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 3. Description: 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) 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. 4.
