openSUSE Security Update : krb5 (krb5-740)

critical Nessus Plugin ID 40017
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 openSUSE host is missing a security update.

Description

Clients sending negotiation requests with invalid flags could crash the kerberos server (CVE-2009-0845).

GSS-API clients could crash when reading from an invalid address space (CVE-2009-0844).

Invalid length checks could crash applications using the kerberos ASN.1 parser (CVE-2009-0847).

Under certain circumstances the ASN.1 parser could free an uninitialized pointer which could crash a kerberos server or even lead to execution of arbitrary code (CVE-2009-0846).

Solution

Update the affected krb5 packages.
