Mandriva Linux Security Advisory : openssl (MDVSA-2011:137)

Medium Nessus Plugin ID 56325


The remote Mandriva Linux host is missing one or more security updates.


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: products_id=490

The updated packages have been patched to correct these issues.


Update the affected packages.
