Summary

MIT kerberos krb5 was updated to fix several security issues and bugs. Security issues fixed: CVE-2014-5351: The kadm5_randkey_principal_3 function in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5) sent old keys in a response to a -randkey -keepold request, which allowed remote authenticated users to forge tickets by leveraging administrative access. CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after gss_process_context_token() is used to process a valid context deletion token, the caller was left with a security context handle containing a dangling pointer. Further uses of this handle would have resulted in use-after-free and double-free memory access violations. libgssrpc server applications such as kadmind were vulnerable as they can be instructed to
