## Description

Double free vulnerability in the krb5\_def\_store\_mkey function in
lib/kdb/kdb\_default.c in MIT Kerberos 5 (krb5) 1.5 has unknown impact and
remote authenticated attack vectors. NOTE: the free operations occur in
code that stores the krb5kdc master key, and so the attacker must have
privileges to store this key.
