Descriptions

The allow_execmod plugin for setroubleshoot before 3.2.23 allows local users to execute arbitrary commands by triggering an execmod SELinux denial with a crafted binary filename, related to the commands.getstatusoutput function.

El complemento allow_execmod para setroubleshoot en versiones anteriores a 3.2.23 permite a los usuarios locales ejecutar comandos arbitrarios al activar una denegación de SELinux de execmod con un nombre de archivo binario manipulado, relacionado con la función commands.getstatusoutput.

A shell command injection flaw was found in the way the setroubleshoot allow_execmod plugin executed external commands. A local attacker able to trigger an execmod SELinux denial could use this flaw to execute arbitrary code with root privileges.
