New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

This update fixes several security issues in openssl :

- The ssl3_get_record function in ssl/s3_pkt.c in OpenSSL 0.9.8f through 0.9.8m allows remote attackers to cause a denial of service (crash) via a malformed record in a TLS connection (CVE-2010-0740)

- OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls which has unspecified impact and context-dependent attack vectors (CVE-2009-3245)

- The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, could allow remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) (CVE-2010-0433)

- Finally, this update provides support for secure renegotiation, preventing men-in-the-middle attacks (CVE-2009-3555).

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

Update :

Packages for 2009.0 are provided due to the Extended Maintenance Program.

Solution
