Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Directory traversal vulnerability in sandbox/win/src/named_pipe_dispatcher.cc in Google Chrome before 33.0.1750.117 on Windows allows attackers to bypass intended named-pipe policy restrictions in the sandbox via vectors related to (1) lack of checks for .. (dot dot) sequences or (2) lack of use of the \\?\ protection mechanism.
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
