Current Description

Buffer overflow in the krbv4_ldap_auth function in servers/slapd/kerberos.c in OpenLDAP 2.4.3 and earlier, when OpenLDAP is compiled with the --enable-kbind (Kerberos KBIND) option, allows remote attackers to execute arbitrary code via an LDAP bind request using the LDAP_AUTH_KRBV41 authentication method and long credential data.

Evaluator Solution

Successful exploitation requires that OpenLDAP allows the use of the LDAPv2 protocol, and is compiled with the --enable-kbind (Kerberos KBIND) option which has been disabled by default since version 2.0.2 and was removed from the configure script in the 2.1 release.

Vendor Statements (disclaimer)

Official Statement from Red Hat (12/19/2006)

Not vulnerable. OpenLDAP as shipped with Red Hat Enterprise Linux 2.1, 3, and 4 does not support the LDAP_AUTH_KRBV41 authentication method.
