Detail

Synopsis

Multiple Denial of Service vulnerabilities have been reported in OpenLDAP.

Background

OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol.

Description

The following errors have been discovered in OpenLDAP:

* Tony Blake discovered an error which exists within the normalisation of "objectClasses" (CVE-2007-5707).

* Thomas Sesselmann reported that, when running as a proxy-caching server the "add_filter_attrs()" function in servers/slapd/overlay/pcache.c does not correctly NULL terminate "new_attrs" (CVE-2007-5708).

* A double-free bug exists in attrs_free() in the file servers/slapd/back-bdb/modrdn.c, which was discovered by Jonathan Clarke (CVE-2008-0658).

Impact

A remote attacker can cause a Denial of Serivce by sending a malformed
"objectClasses" attribute, and via unknown vectors that prevent the
"new_attrs" array from being NULL terminated, and via a modrdn operation with a NOOP (LDAP_X_NO_OPERATION) control.

Workaround

There is no known workaround at this time.

Resolution

All OpenLDAP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nds/openldap-2.3.41"
