The vulnerabilities are caused due to input validation errors when extracting tar archives. This can be exploited to extract files to arbitrary locations outside the specified directory with the permissions of the application using the tarfile module by using the "../" directory traversal sequence or malicious symlinks in a specially crafted tar archive. The vulnerabilities are reported in Python 2.5. Other versions may also be affected. SOLUTION: Do not extract untrusted tar archives.
