openSUSE Security Update : krb5 (openSUSE-2015-128)

high Nessus Plugin ID 81304
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

krb5 was updated to fix five security issues.

These security issues were fixed :

- CVE-2014-5351: current keys returned when randomizing the keys for a service principal (bnc#897874)

- CVE-2014-5352: An authenticated attacker could cause a vulnerable application (including kadmind) to crash or to execute arbitrary code (bnc#912002).

- CVE-2014-9421: An authenticated attacker could cause kadmind or other vulnerable server application to crash or to execute arbitrary code (bnc#912002).

- CVE-2014-9422: An attacker who possess the key of a particularly named principal (such as 'kad/root') could impersonate any user to kadmind and perform administrative actions as that user (bnc#912002).

- CVE-2014-9423: An attacker could attempt to glean sensitive information from the four or eight bytes of uninitialized data output by kadmind or other libgssrpc server application. Because MIT krb5 generally sanitizes memory containing krb5 keys before freeing it, it is unlikely that kadmind would leak Kerberos key information, but it is not impossible (bnc#912002).

This non-security issue was fixed :

- Work around replay cache creation race (bnc#898439).

Solution

Update the affected krb5 packages.
