GLSA-200611-25 : OpenLDAP: Denial of Service vulnerability

medium Nessus Plugin ID 23747


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200611-25 (OpenLDAP: Denial of Service vulnerability)

Evgeny Legerov has discovered that the truncation of an incoming authcid longer than 255 characters and ending with a space as the 255th character will lead to an improperly computed name length. This will trigger an assert in the libldap code.
Impact :

By sending a BIND request with a specially crafted authcid parameter to an OpenLDAP service, a remote attacker can cause the service to crash.
Workaround :

There is no known workaround at this time.


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