Debian Security Advisory DSA 393-1 security@debian.org

--------------------------------------------------------------------------

Package : openssl
Vulnerability : denial of service
Problem-Type : remote
Debian-specific: no
CVE Ids : CAN-2003-0543 CAN-2003-0544

Dr. Stephen Henson (steve@openssl.org), using a test suite provided by
NISCC (www.niscc.gov.uk), discovered a number of errors in the OpenSSL
ASN1 code. Combined with an error that causes the OpenSSL code to parse
client certificates even when it should not, these errors can cause a
denial of service (DoS) condition on a system using the OpenSSL code,
depending on how that code is used. For example, even though apache-ssl
and ssh link to OpenSSL libraries, they should not be affected by this
vulnerability. However, other SSL-enabled applications may be
vulnerable and an OpenSSL upgrade is recommended.

For the current stable distribution (woody) these problems have been
fixed in version 0.9.6c-2.woody.4

For the unstable distribution (sid) these problems have been fixed in
version 0.9.7c-1

We recommend that you update your openssl package. Note that you will
need to restart services which use the libssl library for this update
to take effect.

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.
