| 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.

| Upgrade |
To upgrade automatically, use MandrivaUpdate.
| Verification |
Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command :
rpm --checksig package.rpm
You can get the GPG public key of the Mandriva Security Team to verify the GPG signature of each RPM.
If you use MandrivaUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.
