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.
