 * 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.
 * CVE-2010-1323 / MITKRB5-SA-2010-007: Fixed multiple checksum handling vulnerabilities, where: o krb5 clients might have accepted unkeyed SAM-2 challenge checksums o krb5 might have accepted KRB-SAFE checksums with low-entropy derived keys
 * CVE-2010-1321, MITKRB5-SA-2010-005: Fixed GSS-API library null pointer dereference
