    Kerberos is a network authentication system, which can improve the security of your network by eliminating     the insecure practice of sending passwords over the network in unencrypted form. It allows clients and     servers to authenticate to each other with the help of a trusted third party, the Kerberos key     distribution center (KDC).

    Security Fix(es):

    * krb5: Memory leak at /krb5/src/lib/rpc/pmap_rmt.c (CVE-2024-26458)
