Descriptions
ext/common/ServerInstanceDir.h in Phusion Passenger gem before 4.0.6 for Ruby allows local users to gain privileges or possibly change the ownership of arbitrary directories via a symlink attack on a directory with a predictable name in /tmp/.
ext/common/ServerInstanceDir.h en Phusion Passenger gem anteriores a 4.0.6 para Ruby permite a usuarios locales obtener privilegios o posiblemente cambiar el propietario de directorios arbitrarios a través de un ataque de enlaces simbólicos sobre un directorio con nombre predecible en /tmp/.
rubygem-passenger is a web server for Ruby, Python and Node.js applications. The rubygem-passenger gem created and re-used temporary directories and files in an insecure fashion. A local attacker could use these flaws to conduct a denial of service attack, take over the operation of the application or, potentially, execute arbitrary code with the privileges of the user running rubygem-passenger. Note: By default, OpenShift Enterprise uses polyinstantiation for the /tmp/ directory, thereby minimizing the risk and impact of exploitation by local attackers of both CVE-2013-2119 and CVE-2013-4136.
