Mandriva Linux Security Advisory MDVSA-2011:137
http://www.mandriva.com/security/
_______________________________________________________________________

Package : openssl
Date : September 28, 2011
Affected: 2010.1, 2011.
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in openssl:

The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and
earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA)
is used for the ECDHE_ECDSA cipher suite, does not properly implement
curves over binary fields, which makes it easier for context-dependent
attackers to determine private keys via a timing attack and a lattice
calculation (CVE-2011-1945).

crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not
initialize certain structure members, which makes it easier for
remote attackers to bypass CRL validation by using a nextUpdate value
corresponding to a time in the past (CVE-2011-3207).

The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through
0.9.8s and 1.0.x before 1.0.0e does not ensure thread safety during
processing of handshake messages, which allows remote attackers
to cause a denial of service (application crash) via out-of-order
messages that violate the TLS protocol (CVE-2011-3210).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:

The updated packages have been patched to correct these issues.
