Hi,

I saw today two CVE on OpenLDAP:

• http://vigilance.fr/vulnerability/OpenLDAP-NULL-pointer-dereference-via-dere...
• http://vigilance.fr/vulnerability/OpenLDAP-use-after-free-via-Matched-Values...

Don't know if they are reported in some ITS.

That's because you're reading 2nd or 3rd-hand reports. Read the actual CVEs and you'll see that relevant ITSs already linked.

Given that the deref overlay isn't even documented and is probably used by only a handful of OpenLDAP developers I don't believe it even merited a CVE record.

Hmm, not sure. Arthur de Jong implemented support for this control in nss-pam-ldapd a year ago [1] and IIRC also discussed it on the openldap-technical mailing list.

Ciao, Michael.

* [c6c317e] : Implement deref control handling

This uses the LDAP_CONTROL_X_DEREF control as described in draft-masarati-ldap-deref-00 to request the LDAP server to dereference group member attribute values to uid attribute values. [..]
