Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: openssl
Advisory ID: MDKSA-2003:035
Date: March 25th, 2003
Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0, 9.1,
Corporate Server 2.1,
Multi Network Firewall 8.2,
Single Network Firewall 7.2
________________________________________________________________________
Problem Description:
Researchers discovered a timing-based attack on RSA keys that OpenSSL
is generally vulnerable to, unless RSA blinding is enabled. Patches
from the OpenSSL team have been applied to turn RSA blinding on by
default.
An extension of the "Bleichenbacher attack" on RSA with PKS #1 v1.5
padding as used in SSL 3.0 and TSL 1.0 was also created by Czech
cryptologists Vlastimil Klima, Ondrej Pokorny, and Tomas Rosa. This
attack requires the attacker to open millions of SSL/TLS connections to
the server they are attacking. This is done because the server's
behaviour when faced with specially crafted RSA ciphertexts can reveal
information that would in effect allow the attacker to perform a single
RSA private key operation on a ciphertext of their choice, using the
server's RSA key. Despite this, the server's RSA key is not
compromised at any time. Patches from the OpenSSL team modify SSL/TLS
server behaviour to avoid this vulnerability.

To upgrade automatically, use MandrakeUpdate. The verification of md5
checksums and GPG signatures is performed automatically for you.
If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
FTP mirrors can be obtained from:
http://www.mandrakesecure.net/en/ftp.php
Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:
rpm --checksig <filename>
All packages are signed by MandrakeSoft for security. You can obtain
the GPG public key of the Mandrake Linux Security Team from:
https://www.mandrakesecure.net/RPM-GPG-KEYS
Please be aware that sometimes it takes the mirrors a few hours to
update.
