Package        : openssl096
Problem-Type   : local
Vulnerability  : cryptographic weakness
Debian-specific: no
CVE ID         : CVE-2006-4339
BugTraq ID     : 19849
Debian Bug     : 386247

Daniel Bleichenbacher discovered a flaw in OpenSSL cryptographic package
that could allow an attacker to generate a forged signature that OpenSSL
will accept as valid.

For the stable distribution (sarge) this problem has been fixed in
version 0.9.6m-1sarge2

This package exists only for compatibility with older software, and is
not present in the unstable or testing branches of Debian.

We recommend that you upgrade your openssl packages.  Note that services
linking against the openssl shared libraries will need to be restarted.
Common examples of such services include most Mail Transport Agents, SSH
servers, and web servers.

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.
