(*) marked packages are only affected if certain build

Appendix below for details.
Description:
According to an OpenSSL [0] security advisory [1], multiple
vulnerabilities exist in OpenSSL versions up to and including 0.9.6j
and 0.9.7b:
1. Certain ASN.1 encodings that are rejected as invalid by the ASN.1
parser can trigger a bug in the deallocation of the corresponding
data structure, corrupting the stack.
2. Unusual ASN.1 tag values can cause an out of bounds read under
certain circumstances.
3. A malformed public key in a certificate will crash the verify code
if it is set to ignore public key decoding errors (which is usually
not the case, except for debugging purposes).
4. Due to an error in the SSL/TLS protocol handling, a server will
parse a client certificate when one is not specifically requested.
This means that all OpenSSL based SSL/TLS servers can be attacked
using vulnerabilities 1, 2 and 3 even if they don't enable client
authentication.
The Common Vulnerabilities and Exposures (CVE) project assigned the
ids CAN-2003-0543 [2], CAN-2003-0544 [3] and CAN-2003-0545 [4] to the
problems.
Please check whether you are affected by running "<prefix>/bin/rpm -q
openssl". If you have the "openssl" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution) and it's dependent packages (see above), too. [5][6]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror
location, verify its integrity [11], build a corresponding binary
RPM from it [5] and update your OpenPKG installation by applying the
binary RPM [6]. For the current release OpenPKG 1.3, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.3/UPD
ftp> get openssl-0.9.7b-1.3.2.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig openssl-0.9.7b-1.3.2.src.rpm
$ <prefix>/bin/rpm --rebuild openssl-0.9.7b-1.3.2.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/openssl-0.9.7b-1.3.2.*.rpm
Additionally, we you have to rebuild and reinstall all dependent
packages (see above), too. [5][6]

Appendix:
Some packages are only affected if certain package options
("with_xxx") were used at build time. Please check whether you are
affected by running "<prefix>/bin/rpm -qi <package>". The table below
lists all those packages, their options and values that make up the
difference regarding this advisory for OpenPKG CURRENT, 1.3 and 1.2.
Packages or options that were not available in a particular release
are marked "=".
