    Package        : gnupg
    Problem type   : printf format attack
                     web of trust pollution
    Debian-specific: no
    
    The version of GnuPG (GNU Privacy Guard, an OpenPGP implementation)
    as distributed in Debian GNU/Linux 2.2 suffers from two problems:
    
    fish stiqz reported on bugtraq that there was a printf format
    problem in the do_get() function: it printed a prompt which included
    the filename that was being decrypted without checking for
    possible printf format attacks. This could be exploited by tricking
    someone into decrypting a file with a specially crafted filename.
    
    The second bug is related to importing secret keys: when gnupg
    imported a secret key it would immediately make the associated
    public key fully trusted which changes your web of trust without
    asking for a confirmation. To fix this you now need a special
    option to import a secret key.
    
    Both problems have been fixed in version 1.0.6-0potato1.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    
    Debian GNU/Linux 2.2 alias potato
