Description Marcus Meissner 2018-01-16 14:46:16 UTC

CVE-2018-5710

An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The
pre-defined function "strlen" is getting a "NULL" string as a parameter value in
plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center
(KDC), which allows remote authenticated users to cause a denial of service
(NULL pointer dereference) via a modified kadmin client.

So far, there is no upstream fix available.

Comment 3 Marcus Meissner 2018-11-29 16:00:47 UTC

this seems still unfixed.

Comment 5 Samuel Cabrero 2019-07-23 13:58:44 UTC

I am reassigning to the security team as I think this was fixed as CVE-2018-5729 and CVE-2018-5730 so this one can be closed.

Comment 6 Marcus Meissner 2019-09-04 12:31:33 UTC

Closing, as this was fixed under CVE-2018-5729 and CVE-2018-5730.
