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 Fedora host is missing a security update.Description
This update incorporates patches to fix potential read overflow and NULL pointer dereferences in the implementation of the SPNEGO GSSAPI mechanism (CVE-2009-0844, CVE-2009-0845), attempts to free an uninitialized pointer during protocol parsing (CVE-2009-0846), and a bug in length validation during protocol parsing (CVE-2009-0847).Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected krb5 package.See Also
