CVE-2013-2119: Incorrect temporary file usage

January 3, 2014 (updated December 6, 2016)

The passenger ruby gem, when used in standalone mode, does not use temporary files securely. If a local attacker were able to create a temporary directory that passenger uses and supply a custom nginx configuration file they could start a nginx instance with their own configuration file.
