Google Chrome before 50.0.2661.102 on Android mishandles / (slash) and \ (backslash) characters, which allows attackers to conduct directory traversal attacks via a file: URL, related to net/base/escape.cc and net/base/filename_util.cc.

The version of Google Chrome for Android on the remote mobile host is prior to 50.0.2661.102 and thus unpatched for a flaw in the 'FileURLToFilePath()' function in 'net/base/filename_util.cc' that allows traversing outside of a restricted path.  The issue is due to the program not properly sanitizing user input, specifically path traversal style attacks (e.g. '../') supplied via the file scheme.  This may allow an attacker to have an unspecified impact.
