CVE-2013-2119

Phusion Passenger gem before 3.0.21 and 4.0.x before 4.0.5 for Ruby allows local users to cause a denial of service (prevent application start) or gain privileges by pre-creating a temporary "config" file in a directory with a predictable name in /tmp/ before it is used by the gem.

Phusion Passengers code did not always create temporary files and directories in a secure manner. Temporary files and directories were sometimes created with a predictable filename. A local attacker can pre-create temporary files, resulting in a denial of service. In addition, this vulnerability allows a local attacker to run arbitrary code as another user, by hijacking temporary files (CVE-2013-2119).

The rubygem-passenger package has been upgraded to version 3.0.21, which fixes this issue, as well as many others although at the moment has further issues which will be fixed with another update (mga#10728).

These are all security issues fixed in the ruby2.7-rubygem-passenger-6.0.8-3.2 package on the GA media of openSUSE Tumbleweed.

This update fixes the following security issues:

• CVE-2015-7519: Passenger is not filtering environment like apache is doing (bnc#956281)

• CVE-2013-4136: Fixed security issue Passenger would reuse existing server instance directories (temporary directories) which could cause Passenger to remove or overwrite files belonging to other instances. Solution: If the server instance directory already exists, it will now be removed first in order get correct directory permissions. If the directory still exists after removal, Phusion Passenger aborts to avoid writing to a directory with unexpected permissions.(bnc#919726)

• CVE-2013-2119: Fixed security issue related with incorrect temporary file usage (bnc#828005)
