10 CVE-2007-5972 119 Overflow 2007-12-05 2010-05-27
9.0
 Admin Remote Low Single system Complete Complete Complete
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.
11 CVE-2007-5902 189 Overflow 2007-12-05 2010-05-27
10.0
 Admin Remote Low Not required Complete Complete Complete

12 CVE-2007-5894 2007-12-05 2008-11-15
9.3
 Admin Remote Medium Not required Complete Complete Complete
** DISPUTED ** The reply function in ftpd.c in the gssftp ftpd in MIT Kerberos 5 (krb5) does not initialize the length variable when auth_type has a certain value, which has unknown impact and remote authenticated attack vectors. NOTE: the original disclosure misidentifies the conditions under which the uninitialized variable is used. NOTE: the vendor disputes this issue, stating " The 'length' variable is only uninitialized if 'auth_type' is neither the 'KERBEROS_V4' nor 'GSSAPI'; this condition cannot occur in the unmodified source code."
