nss_ldap is a Name Service Switch module which allows 'passwd', 'group'
|
|
and 'host' database information to be pulled from LDAP.

<description>

|
<p>
|
|
Josh Burley reported that nss_ldap does not properly handle the LDAP
|
|
connections due to a race condition that can be triggered by
|
|
multi-threaded applications using nss_ldap, which might lead to
|
|
requested data being returned to a wrong process.
|
|
</p>
|
|
</description>
|
|
<impact type="low">
|
|
<p>
|
|
Remote attackers could exploit this race condition by sending queries
|
|
to a vulnerable server using nss_ldap, possibly leading to theft of
|
|
user credentials or information disclosure (e.g. Dovecot returning
|
|
wrong mailbox contents).
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All nss_ldap users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-auth/nss_ldap-258"</code>
|
|
</resolution>
