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 type="normal">
|
|
<p>
|
|
By sending a BIND request with a specially crafted authcid parameter to
|
|
an OpenLDAP service, a remote attacker can cause the service to crash.

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<resolution>
|
|
<p>
|
|
All OpenLDAP users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose "net-nds/openldap"</code>
|
