CVE-2019-11879: Path Traversal
First published: Fri May 10 2019(Updated: )
** DISPUTED ** The WEBrick gem 1.4.2 for Ruby allows directory traversal if the attacker once had local access to create a symlink to a location outside of the web root directory. NOTE: The vendor states that this is analogous to Options FollowSymlinks in the Apache HTTP Server, and therefore it is "not a problem."
