title: Uploading & extracting archive (zip, rar, targz, tarbz) automatically - security issue?
body: <p>I'd like to create following functionality for my web-based application:</p>
  
  <ol>
  <li>user uploads an archive file (zip/rar/tar.gz/tar.bz etc) (content - several image files)</li>
  <li>archive is automatically extracted after upload</li>
  <li>images are shown in the HTML list (whatever)</li>
  </ol>
  
  <p>Are there any security issues involved with extraction process? E.g. possibility of malicious code execution contained within uploaded files (or well-prepared archive file), or else?</p>
