    A directory traversal vulnerability in UnZip 5.50 allows attackers to
    bypass a check for relative pathnames ("../") by placing certain invalid
    characters between the two "." characters.
    
    For the stable distribution (woody) this problem has been fixed in
    version 5.50-1woody1.
    
    For the unstable distribution (sid) this problem will be fixed soon.
    
    We recommend that you update your unzip package.
