Description Andrej Nemec 2017-04-25 13:11:42 UTC

A file overwrite vulnerability was found in passenger caused by a predictable temporary file being written by passenger-install-nginx-module. With access to the system, a user could plant a symlink in /tmp that resulted in a chosen-file overwrite attempt whenever passenger-install-nginx-module was run, using the access rights of the executing user, potentially even with chosen content.

Comment 2 Tomas Hoger 2017-04-27 18:23:50 UTC

This issue does not affect passenger packages in RHSCL, Fedora, and EPEL, as they do not include the affected passenger-install-nginx-module script. The script is removed during the package build, see e.g.:
