Package        : openssl094
Vulnerability  : cryptographic weakness
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2005-2969

Yutaka Oiwa discovered a vulnerability in the Open Secure Socket Layer
(OpenSSL) library that can allow an attacker to perform active
protocol-version rollback attacks that could lead to the use of the
weaker SSL 2.0 protocol even though both ends support SSL 3.0 or TLS
1.0.

The following matrix explains which version in which distribution has
this problem corrected.

                oldstable (woody)      stable (sarge)     unstable (sid)
openssl          0.9.6c-2.woody.8       0.9.7e-3sarge1      0.9.8-3
openssl 094      0.9.4-6.woody.4             n/a              n/a
openssl 095      0.9.5a-6.woody.6            n/a              n/a
openssl 096           n/a               0.9.6m-1sarge1        n/a
openssl 097           n/a                    n/a            0.9.7g-5

We recommend that you upgrade your libssl 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
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
