    Daniel Stenberg discovered that wget, a network utility to retrieve files from
    the Web using http(s) and ftp, is vulnerable to the "Null Prefix Attacks Against
    SSL/TLS Certificates" published at the Blackhat conference some time ago.  This
    allows an attacker to perform undetected man-in-the-middle attacks via a crafted
    ITU-T X.509 certificate with an injected null byte in the Common Name field.
    
    
    For the oldstable distribution (etch), this problem has been fixed in
    version 1.10.2-2+etch1.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.11.4-2+lenny1.
    
    For the testing distribution (squeeze), this problem will be fixed soon.
    
    For the  unstable distribution (sid), this problem has been fixed in
    version 1.12-1.
    
    
    We recommend that you upgrade your wget packages.
    
    
    Upgrade instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
