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.


Upgrade Instructions
- - --------------------

wget url
        will fetch the file for you

        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
        will update the internal database
