1 CVE-2009-0846 20 DoS Exec Code 2009-04-09 2020-01-21
10.0
None Remote Low Not required Complete Complete Complete
The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
2 CVE-2009-0844 119 DoS Overflow +Info 2009-04-09 2020-01-21
5.8
None Remote Medium Not required Partial None Partial
The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to cause a denial of service (daemon crash) and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read.
3 CVE-2007-5902 189 Overflow 2007-12-06 2020-01-21
10.0
None Remote Low Not required Complete Complete Complete
Integer overflow in the svcauth_gss_get_principal function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (krb5) allows remote attackers to have an unknown impact via a large length value for a GSS client name in an RPC request.
4 CVE-2007-5894 2007-12-06 2020-01-21
9.3
None 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."
5 CVE-2007-3149 +Priv 2007-06-11 2020-01-21
7.2
None Local Low Not required Complete Complete Complete
sudo, when linked with MIT Kerberos 5 (krb5), does not properly check whether a user can currently authenticate to Kerberos, which allows local users to gain privileges, in a manner unintended by the sudo security model, via certain KRB5_ environment variable settings. NOTE: another researcher disputes this vulnerability, stating that the attacker must be "a user, who can already log into your system, and can already use sudo."
6 CVE-1999-0713 +Priv 1999-06-11 2020-01-21
7.2
None Local Low Not required Complete Complete Complete
The dtlogin program in Compaq Tru64 UNIX allows local users to gain root privileges.
7 CVE-1999-0143 1996-02-21 2020-01-21
4.6
None Local Low Not required Partial Partial Partial
Kerberos 4 key servers allow a user to masquerade as another by breaking and generating session keys.
