    Debian Bug     : 766981
    
    HD Moore of Rapid7 discovered a symlink attack in Wget, a command-line 
    utility to retrieve files via HTTP, HTTPS, and FTP. The vulnerability 
    allows to create arbitrary files on the user's system when Wget runs in 
    recursive mode against a malicious FTP server. Arbitrary file creation 
    may override content of user's files or permit remote code execution with 
    the user privilege. 
    
    This update changes the default setting in Wget such that it no longer 
    creates local symbolic links, but rather traverses them and retrieves the 
    pointed-to file in such a retrieval.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.13.4-3+deb7u2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.16-1.
    
    We recommend that you upgrade your wget packages.
