    MIT krb5 a popular implementation of Kerberos 5 protocol was     affected by a vulnerability.

    An authenticated attacker can cause kadmind to write beyond     the end of the mapped region for the iprop log file, likely causing a     process crash.

    For Debian 11 bullseye, this problem has been fixed in version     1.18.3-6+deb11u6.

    We recommend that you upgrade your krb5 packages.

    For the detailed security status of krb5 please refer to     its security tracker page at:
