Detailsinfo

A vulnerability classified as critical has been found in Google Chrome 28.0.1500.95 (Web Browser). This affects the function filepath::referencesparent of the file files/file_path.cc. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The FilePath::ReferencesParent function in files/file_path.cc in Google Chrome before 29.0.1547.57 on Windows does not properly handle pathname components composed entirely of . (dot) and whitespace characters, which allows remote attackers to conduct directory traversal attacks via a crafted directory name.
