Vulnerability Assessment Details

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

Vulnerability Assessment Summary
OpenLDAP: Denial of Service vulnerability

Detailed Explanation for this Vulnerability Assessment
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.
