SUSE SLES12 Security Update : krb5 (SUSE-SU-2015:1276-1)

medium Nessus Plugin ID 84914
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 SUSE host is missing one or more security updates.

Description

krb5 was updated to fix four security issues.

These security issues were fixed :

- CVE-2014-5353: NULL pointer dereference when using a ticket policy name as password name (bsc#910457).

- CVE-2014-5354: NULL pointer dereference when using keyless entries (bsc#910458).

- CVE-2014-5355: Denial of service in krb5_read_message (bsc#918595).

- CVE-2015-2694: OTP and PKINIT kdcpreauth modules leading to requires_preauth bypass (bsc#928978).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
