    Package        : libcrypt-cbc-perl
    Vulnerability  : programming error
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2006-0898
    
    Lincoln Stein discovered that the Perl Crypt::CBC module produces weak
    ciphertext when used with block encryption algorithms with blocksize >
    8 bytes.
    
    The old stable distribution (woody) does not contain a Crypt::CBC module.
    
    For the stable distribution (sarge) this problem has been fixed in
    version 2.12-1sarge1.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 2.17-1.
    
    We recommend that you upgrade your libcrypt-cbc-perl package.
