This update of krb5 applications fixes two security issues.
CVE-2011-4862: A remote code execution in the kerberized telnet daemon was fixed. (This only affects the ktelnetd from the krb5-appl RPM, not the regular telnetd supplied by SUSE.)
CVE-2011-1526 / MITKRB5-SA-2011-005: Fixed krb5 ftpd unauthorized file access problems.
