high Nessus Plugin ID 77644
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

Updated krb5 package fixes security vulnerabilities :

MIT Kerberos 5 allows attackers to cause a denial of service via a buffer over-read or NULL pointer dereference, by injecting invalid tokens into a GSSAPI application session (CVE-2014-4341, CVE-2014-4342).

MIT Kerberos 5 allows attackers to cause a denial of service via a double-free flaw or NULL pointer dereference, while processing invalid SPNEGO tokens (CVE-2014-4344).

In MIT Kerberos 5, when kadmind is configured to use LDAP for the KDC database, an authenticated remote attacker can cause it to perform an out-of-bounds write (buffer overflow) (CVE-2014-4345).

Solution

Update the affected packages.
